Machines vs. Free Weights

Monday, March 30th, 2009

A common conundrum facing the weight training neophyte (that’s newbie for you… well, uh… newbies) is the age old debate machines vs. free weights. Which form of resistance exercise is better? Which method of weight training is safer? What about bands and tubing? Where do they fit into the equation?

Let’s try and take a hard look at all these modes and give you some insight. First, you have to consider all exercise as resistance training. Yes, even your leisurely jog on the treadmill or elliptical machine are resistance-based exercises. As long as any movement is performed within the confines of the earth’s gravitational pull, then it’s a resistance-based exercise. It’s just physics folks not opinion, don’t bother trying to argue. Very good, now let’s take a look at some of the pros and cons of each method.

Machine-Based Resistance (not cables)

Pros

  • Relatively easy to use, not much thought required to push/pull on a lever
  • Usually come with some kind of instruction placard/sign
  • Wide range of machines to “target” almost every muscle group
  • Provide opportunity for incremental load progressions. In other words, it allows you to easily change the weight
  • Can be perceived as less intimidating/safer by new users

Cons

  • Most machines have very limited range adjustments (usually seat height only) forcing the user to adjust his/her body to the machine, not the other way around
  • To be used effectively and safely, machines demand a sound understanding of the principles related to anatomical ranges of motion and joint mechanics
  • Increased risk of injury due to repetitive inappropriate application of force through joints (the machine’s joints are certainly stronger than your own!)
  • Will limit your development if used exclusively

Free Weights and Cables

Pros

  • Provide the widest selection of movements and exercises
  • When used appropriately can create an extremely effective muscular stimulus far in excess of what can be achieved with most machines (i.e. standing vs. sitting)
  • Due to increased neural demand placed on muscles during use, should promote greater gains (i.e. fat loss, muscle growth and strength increases)
  • Accommodation of special requirements (i.e. existing orthopaedic/postural pathologies) more readily accomplished

Cons

  • Big, heavy iron weights can often seem intimidating and frightening (common concern with many females)
  • Lack of instruction placards can leave a new user unsure of where to begin
  • Sheer lack of options available can cause confusion and uncertainty

As always there is no right or wrong choice. Both machine and free-weight training  are options and tools limited only by the skill and experience of the operator. One does not have a clear superiority over the other. In fact, both approaches have a place in your overall and complete development. Your success is predicated on taking the time to seek proper instruction and education before attempting any exercise on your own.  More information is always better than less.

Muscle Building Nutrition Q&A – Part 3

Sunday, March 29th, 2009

Continuing on with the answers to the following questions …

How long should I bulk?

How long do I have to bulk?

(again, I am just using the term ‘bulk’, which I dislike to indicate a primary focus on gaining muscle)

The first ‘it depends’ answer was to counter with the question of how much muscle do you want to gain?

To that we add the following:

2. How much muscle do you gain when eating in a caloric surplus and how much fat you gain when eating in a caloric surplus – or basically your muscle-to-fat-gain ratio. This basically refers to one’s partitioning ability – simply where the extra calories go. Does it wind up in muscle cells or fat cells? Ideally all of it would go to muscle, but sorry, not gonna happen. You might as well accept it now.

Now ideally at least more of the extra calories are partitioned towards muscle than they are towards fat. What affects this? First and foremost, genetics. Some people simply partition more calories towards muscle than others do. The less fortunate partition more calories towards fat cells than they do muscle. So on the one hand you might have someone gaining more muscle for a given weight gain and some gaining more fat than muscle (sucks!) for a given weight gain.

So we have things like the aforementioned genetics, higher-than-normal testosterone levels and other optimally ranged hormones (lower cortisol responses, healthy thyroid levels, etc) as well as good insulin sensitivity in the muscles.

Scientists refer to something called the p-ratio when discussing the partitioning of calories. The p-ratio is again, largely influenced by genetic factors and varies little within a person. Diet, training, etc (basically lifestyle factors) have the potential to influence it about 5-15% – not very much.

So, that tells us there’s not a lot you can do to shift your own innate muscle-to-fat-gain ratio (or even your fat-to-muscle-loss ratio when dieting) beyond the relatively small (yet not insignificant) effect nutrition, training (and drugs) has on it.

So we obviously get that diet and training should be on point during a bulk. From a dietary standpoint, you obviously need to be certain you’re eating enough to sustain not only the growth of new muscle tissue but the maintenance of it as well. This is one of the biggest pitfalls of those seeking out more muscle – they don’t eat enough. You can’t build a house out of sweat people. No raw materials? No muscle. Ample caloric intake is the biggest factor to be aware of.

Training of course is important as well, but the supporting growth factors – hormones, caloric intake, etc. – determine how much you can gain and support. Training is just a stimulus. Many think that because they’re training heavy and hard, the muscle is just going to come as a result. Again, it’s just a stimulus – if the supporting growth factors are not there, it’s just not going to happen.

Ok, so this ties into the next point:

3. How much fat are you comfortable gaining? This is going to be determined by one, how much over maintenance you’re eating and two, the aforementioned muscle-to-fat-gain ratio or how well your body partitions extra calories. For those with better partitioning ability, more of their new weight is going to be muscle and less is going to be fat, so they’re probably going to have an easier time of it. For those less fortunate, it’s going to be a different story. They’re going to gain more bodyfat for a given weight gain. How much are you comfortable with gaining? Remember, you’re going to gain some. Expect not to and I guarantee you that you’re going to look exactly the same at the end of your bulk.

These three points are really the determining factors of the length of your bulk – how much muscle do you want/need to gain, how much muscle/fat do you gain when consuming calories in excess of maintenance (a requirement), and how much body fat are you comfortable gaining along the way.

The Final Stretch

Saturday, March 28th, 2009

What’s the deal with stretching? Should you even stretch at all? Ask a bunch of different ‘experts’ get a bunch of different answers! Why all the controversy? There are a host of reasons as to why stretching is considered a hot topic of discussion. Primarily, the debate about stretching stems from the recent re-examination of its potential benefits vs. risks.

Most fitness people will tell you stretching is necessary to maintain or increase flexibility. I’m not convinced. I think flexibility is overrated and often misunderstood; what’s the point of tremendous flexibility if you can’t show strength and stability in these strange or extreme positions? We’ve been conditioned to perceive ‘tightness’ in the body as a bad thing to be avoided at all costs. I however would like you to consider before you go indiscriminately trying to eradicate all tension from your body you might want to consider why it’s there in the first place. Is it possible your body in all of its central nervous systemic wisdom has signaled a muscle to ‘tighten’ for a particular reason? Maybe the muscle is tight to generate enough tension to help maintain joint congruency when a muscle on the other side of the joint axis has stopped pulling its share of the load?

Consider this scenario: You’ve got a tight hamstring that is limiting your ability to get into your favorite Kama Sutra pose so you decide to stretch it out. However, before you throw your leg up on a high bar your ‘partner’ hits you with this pearl of wisdom: “Hey there lover boy, maybe your hamstring tightness is indicative of a weakness somewhere in your quad and it’s your body’s way of keeping things together so you don’t blow out your knee attempting the ‘Mantis Eating Flower’ position?”

Get the picture? Your body is aware of what’s going on inside, and no one, not even you, are consciously aware of what’s happening at all times. The perceived tension might actually be there as a protective measure your body has created to avoid injury. There is really no way of determining for certain what the cause of the tension is. The source could be anything, bony protrusions, ivy, scar tissue, adhesions, neurological discord, etc. To then attempt to treat the symptom of tightness with indiscriminate stretching, self myo-facial release or even massage might be counter-indicated and downright dangerous!

With my clients/patients I typically perform something called Muscle Activation Technique (MAT) positional and strength testing which often gives me a better idea of what might be going on at each joint and its contributing musculature. Using various isometrics and mild palpations we’re usually able to significantly improve one’s range of motion (ROM) and joint stability, which is really what most people are after. MAT is a powerful tool, and should only be performed by a qualified practitioner as the risk of causing harm is enormous. For practitioners in your area check out www.muscleactivation.com

So when should you stretch? Well, I think stretching immediately before activity can be detrimental to force production as it tends to shut muscles down. Limiting force production is probably the last thing you want to do just before training or taking the field for some form of contest or game. Before an event I usually recommend some kind of warm up activity like jumping jacks, push-up or even short sprints for example. As a warm up to a workout try the movement you’ll be training unloaded. These dynamic movements should get your blood pumping and your joints well lubricated and ready to work, but more importantly you’ll be telling your central nervous system (CNS) it’s time to wake up and get ready to go! That said if you feel you must stretch, save it for after the event or workout or better yet do some cat stretches before bed when you’d likely want your muscles to relax and shut down. I can already hear all you MMA guys and gymnasts “I have to stretch; my coach says it’s for flexibility!” Hey, who am I to argue with a coach! Just keep in mind when you adhere to a regimen of extreme passive stretching typical of most gymnastics and martial arts gyms or dojos you are making a decision to adopt hyper-mobility now for lack of mobility later. Think about that the next time a coach or trainer attempts to put your ankle over your head (I think that IS the ‘Mantis eating flower” position after all!).

“No Pain No Gain” – Doesn’t Mean Risking an Injury

Thursday, March 26th, 2009

There’s good pain and bad pain. Good pain is that stiffness that settles in about 2 days after a hard workout.  Bad pain is any kind of soreness that results from a popping, crunching, tearing or cracking sound. The adage “no pain, no gain” is misunderstood. Yes, adding another plate on the bar is going to cause discomfort, but if done properly, it shouldn’t damage you. Self-assessment of injuries is a necessity at times, but you should always seek a second opinion. And no, your training buddy doesn’t count.

There are a variety of injuries that can occur when training, like sprains or tears that will not improve without a change of exercise or a break form training all together. As much as it hurts, you may have to take a few days off from working out to let your body heal. Better to take a few days off than risk another injury that could mean months or years away from the gym. Remember the weights will still be there next week. Injuries have a tendency to compound themselves, possibly later limiting your mobility or making you prone to re-injury down the road. Take care of it now or it could flare up at the wrong time, like before a competition.

Every injury is unique. Don’t assume because you get advice from a buddy that you’re okay to get back in the gym. Get it checked out now and you can feel safe returning to the gym with the doctor’s say so.

You Are Your Biggest Opponent

Tuesday, March 24th, 2009

Let’s get the New Year started right. That short break between visiting family and getting back to work is a great time to assess the year ahead and set the goals that you want to achieve with your training. We’re not talking about resolutions; we’re way beyond those. We are setting landmarks for your body in the year ahead – with no going back!

The reason that we’re not calling these resolutions is because it’s not about a quick change – it’s about changing our lifestyle. If you’re reading this blog, you’re smart enough to know it isn’t so much about the destination but the journey. Small, achievable goals will keep you moving forward throughout the year. Let’s look at a basic goal, like adding an inch to your chest. You’re not going to achieve this by just hitting the bench harder. There will be diet changes, schedule changes and a re-evaluation of your supplements. No matter what you want to do this year, you’ve got to be ready to do some work. That work takes time, and over time, it helps to be able to check off small marker goals for a sense of accomplishment.

While you may want to add an inch in a year – you’ll want to set goals of a quarter inch – say in 2 months. Use this time to set the goals and record them.

Dream Away Fat with CLA

Wednesday, March 18th, 2009

Conjugated linoleic acid (CLA) is a fatty acid that can be found naturally in meats and dairy products. It is also a popular supplement among bodybuilders for various reasons.Several studies have shown CLA to have antioxidant properties, aid in muscle growth and to help reduce body fat.

A recent study further supports CLA’s fat-fighting properties even while you sleep. Subjects were provided with either 4 grams of CLA a day or a placebo (4 grams of safflower oil) for 6 months. The group taking CLA burned 43 kcal more than the placebo group during sleep. Additionally, subjects taking CLA lost on average 2.2 pounds of fat, while those taking the placebo gained a pound.

While these results may not seem that significant, competitive bodybuilders may want to include CLA into their pre-contest prep to help shed away those last few stubborn pounds of fat, which could mean all the difference from taking home the hardware or walking off stage empty handed.

Finding Balance — Symmetry and You

Monday, March 16th, 2009

Ahhhh! The elusive X-Frame!  Some have it, some want it – and a few lucky bastards are born with it. It’s that symmetrical balance between large, round bellies on the upper torso – a small, tight waist – and big, sweeping quads on the bottom half. For competitive bodybuilding – it’s the deciding factor. But how do you know if you have it? You probably don’t – that’s why you need the help of a brutally honest friend. Your eyes are not good enough – they can play tricks on you. Many tend to suffer from body dysmorphia – when they see something totally different about themselves than everybody else does. It’s a head game no one wins.

To accurately know what areas to work on in order to achieve the symmetry that the judges want to see, you’ll need two things – a friend and a measuring tape. As far a friend goes, use a training buddy to check you out every week to 2 weeks – any more often than that and you’ll officially be dating. In all seriousness, an outside set of eyes will give you the perspective that you cannot see in the mirror. Make sure your partner takes a look at a judging sheet, so he knows what he’s looking for. As you get more experienced, you’ll be better able to assess yourself, but for now, trust a buddy.

Get a measuring tape from a sewing shop. You’ll want one more flexible than the one you would use for a construction job. Measure your arms (flexed and relaxed), chest, back, thighs and calves. Again, get a friend to help. Don’t be concerned if there are minor differences between your limbs; it’s to be expected. This is why you’re doing this. Use this technique every few weeks and record the results. It is a great motivator, but don’t do it too often. It’s easy to become obsessed with small gains and losses.

Lift Fast – The Results are Worth It!

Thursday, March 12th, 2009

The central nervous system (CNS) controls muscle contraction. When the body needs to produce force, such as lifting a weight, the CNS signals an appropriate amount of muscle fibers to contract to get the job done. The more muscle fibers the CNS recruits, the greater the potential for growth. One way to increase the number of muscle fibers recruited is by lifting a weight in an explosive manner. This is due to the fact that it takes more force, and therefore more muscle fibers, to lift a weight in one second than it does in two. If that wasn’t enough reason to train ballistically, recent research has given another.

A study performed at Ball State University was conducted to compare the effects of explosive versus slow contractions on energy expenditure (calorie burning). Subjects performed squats using either explosive (less than one second) or slow (2 seconds) concentric (muscle shortening) contractions, but used the same amount of weight (60% 1RM) and followed the same rep/set scheme (8/4). Results showed that subjects burned 12 percent more calories when they lifted the weight explosively than when they did slowly.

Why You Need To Tan

Monday, March 9th, 2009

It’s time for another reality check by yours truly and this time it’s a discussion on skin tone. OK, well maybe not a discussion – more like a rant. Bodybuilding stages these days seem to be haunted. That’s right. Haunted! More and more often I see lineups on stage with one or two “ghosts” floating through the mandatory poses. No – I’m not having a stroke or on some kind of hallucinogen. I even see some muscular “Caspers” in the fitness and bodybuilding magazines today. Not sure what I’m talking about? It’s people who don’t tan. Many still fail to realize that whether your under the bright lights of the competitive stage or the hot lights of a photo shoot – those puppies can wash you out.

A dark tan is one of the keys to really showing off your muscles and deep cuts. Definition is enhanced with a golden brown glow. And if you’re concerned about UV rays – there is a load of self-tanning creams and sprays out there that get you almost the same results. So there is no reason for you to be depriving yourself of the head-turning power of a good tan. But be careful – as with all things muscle related – it can be overdone.

Tricks of the tan:

  1. A good base of natural tan either via the sun or a tanning booth can help with a good, competitive bronze. Try to start tanning at least 6 weeks out from competition. Then you won’t have to rush it an risk burning or damaging your skin.
  2. With a good base tan – it is still necessary to apply a tanning oil or cream (and several coats at that) prior to stepping on stage. Be sure to check in advance with the regulations of the show you’re in to see if certain oils and creams are banned. When you apply them, having someone else’s assistance always helps. There’s no nice way to put it; you’re painting yourself and the only way to make sure you don’t need another coat is a second set of eyes.
  3. Lindsay Lohan syndrome. If you opt not to chance the UV damage and go with bronzing creams or sprays – choose a pigment that works to make you BROWN – not orange or grey.

Of course, if you still prefer tanning, that option is still open to you. Be sure to start well before the competition to be sure you know your tolerance. Also, certain medications do not react well to the beds, so check with your doctor before you start. Stand up booths take less time but are more expensive. Most salons or gyms will give you your first session free to see which bed you prefer. Whatever you do, darken up in time for the judging – you don’t want the kid from THE 6th SENSE sitting in the crowd whispering “I see white people.”
