Exercise Guide

Isometric exercise means that you push against something that doesn’t move, such as a wall. Thirty years ago, most weightlifters and athletes is sports requiring strength used isometric training to make themselves stronger. Athletes don’t use isometric training much anymore. The strength gained through performing isometric contractions is only within 20 degrees of the angle you hold. On the other hand, when you lift weights, you become strong through a wide range of motion. Isometrics cause your blood pressure to rise higher than the other methods of strength training. If you have weak blood vessels or heart trouble, you can rupture a blood vessel or develop an irregular heart beat.

According to Dr. John D. Fair, Chairman of the Department of History at Auburn University, the popularity of isometrics was the result of the success of some weightlifters who took synthetic male hormones called anabolic steroids and then claimed that their isometric exercises made them strong. They claimed that they were doing a revolutionary new training method of pushing against bars that didn’t move. The steroids made them stronger by helping them to recover faster from tough workouts so they could do more work. The only stimulus to make a muscle stronger is to exercise that muscle against resistance. You can lift heavy weights, push against special strength machines and push against something that doesn’t move, such as a wall or bar attached to the ground. Isometrics are not used much any more, but the steroids are still used, even though they are banned by most sport authorities.

Working as a fitness professional, there is one type of question I get all the time that shows that many people are missing the big picture regarding the benefits of strength training. This popular question usually goes something like this:

“What exercise can I do to isolate my _______ (insert your muscle of choice - abs, quads, biceps, triceps, etc)?”

It doesn’t matter which muscle someone is asking about, they always seem to be asking how to ‘isolate’ it. My first response to this question is always - “Why in the world would you want to isolate it?”

The first thing I try to teach my clients is that the body does not work well in muscle isolation. Rather, it works better in movements along a kinetic chain; that is, large portions of the body assist other portions of the body in completing a complex movement. In fact, there really is no such thing as true muscle isolation. There is almost always a nearby muscle group that will assist in some way with whatever movement you are doing. However, this article compares attempting to ‘isolate’ body parts via single-joint exercises to the much more effective strategy of performing multi-joint complex movements.

When you attempt to ‘isolate’ muscles by performing single-joint exercises, you are actually creating a body that is non-functional and will be more prone to injury. Essentially, you are creating a body that is a compilation of body parts, instead of a powerful, functional unit that works together.

Now if you really want to end up hobbling around in a body bandaged up with joint problems, tendonitis, and excess body fat, then by all means, continue trying to ‘isolate’ body parts. On the other hand, if you would rather have a lean, muscular, injury-free, functional body that works as a complete powerful unit to perform complex movements (in athletics or even everyday tasks), then you need to shift your focus away from muscle isolation. Believe me, focusing on how well your body functions will give you the side effect of a body that looks even better than it would have if you focused on muscle isolation. For example, take a look at the physiques of any NFL running backs, wide receivers, or even world class sprinters. Trust me when I say that these guys pretty much NEVER train for muscle isolation (their strength coaches wouldn’t be crazy enough to let them), yet they are absolutely ripped to shreds! Just look at guys like Maurice Green or Terrell Owens and tell me who wouldn’t want a physique like those guys.

Another benefit to moving away from the ‘muscle isolation’ mindset to a more ‘complex movement’ mindset is that you will find it much easier to lose body fat. The reason is that by focusing more on multi-joint complex movements as opposed to single-joint muscle isolation, you not only burn a lot more calories during each workout, but you also increase your metabolic rate, and stimulate production of more fat burning and muscle building hormones like growth hormone and testosterone.

Let’s look at an example. The machine leg extension is a single joint exercise that works mainly the quadriceps, can potentially cause knee joint instability in the long run, and doesn’t even burn that many calories. On the other hand, exercises like squats, lunges, step-ups, and deadlifts are all multi-joint complex movements that work hundreds of muscles in the body (including the quadriceps) as a functional unit, create more stable and strong joints in the long run (when done properly), and also burn massive quantities of calories compared to the single-joint exercises.

The Front Squat:

As you may have already discovered, the squat is at the top of the heap (along with deadlifts) as one of the most effective overall exercises for stimulating body composition changes (muscle gain and fat loss). This is because exercises like squats and deadlifts use more muscle groups under a heavy load than almost any other weight bearing exercises known to man. Hence, these exercises stimulate the greatest hormonal responses (growth hormone, testosterone, etc.) of all exercises. In fact, university research studies have even proven that inclusion of squats into a training program increases upper body development, in addition to lower body development, even though upper body specific joint movements are not performed during the squat. Whether your goal is gaining muscle mass, losing body fat, building a strong and functional body, or improving athletic performance, the basic squat and deadlift (and their variations) are the ultimate solution. If you don’t believe me that squats and deadlifts are THE basis for a lean and powerful body, then go ahead and join all of the other overweight people pumping away mindlessly for hours on boring cardio equipment. You won’t find long boring cardio in any of my programs!

Squats can be done with any free weighted objects such as barbells, dumbbells, kettlebells, sandbags, or even just body weight. Squats should only be done with free weights - NEVER with a Smith machine or any other squat machines! Machines do not allow your body to follow natural, biomechanically-correct movement paths. You also perform less work because the machine stabilizes the weight for you. Therefore, you get weaker results!

The type of squat that people are most familiar with is the barbell back squat where the bar is resting on the trapezius muscles of the upper back. Many professional strength coaches believe that front squats (where the bar rests on the shoulders in front of the head) and overhead squats (where the bar is locked out in a snatch grip overhead throughout the squat) are more functional to athletic performance than back squats with less risk of lower back injury. I feel that a combination of all three (not necessarily during the same phase of your workouts) will yield the best results for overall muscular development, body fat loss, and athletic performance. Front squats are moderately more difficult than back squats, while overhead squats are considerably more difficult than either back squats or front squats. I’ll cover overhead squats in a future article. If you are only accustomed to performing back squats, it will take you a few sessions to become comfortable with front squats, so start out light. After a couple sessions of practice, you will start to feel the groove and be able to increase the poundage.

To perform front squats:

The front squat recruits the abdominals to a much higher degree for stability due to the more upright position compared with back squats. It is mostly a lower body exercise, but is great for functionally incorporating core strength and stability into the squatting movement. It can also be slightly difficult to learn how to properly rest the bar on your shoulders. There are two ways to rest the bar on the front of the shoulders. In the first method, you step under the bar and cross your forearms into an “X” position while resting the bar on the dimple that is created by the shoulder muscle near the bone, keeping your elbows up high so that your upper arms are parallel to the ground. You then hold the bar in place by pressing the thumb side of your fists against the bar for support.

Alternatively, you can hold the bar by placing your palms face up and the bar resting on your fingers against your shoulders. For both methods, your elbows must stay up high to prevent the weight from falling. Your upper arms should stay parallel to the ground throughout the squat. Find out which bar support method is more comfortable for you. Then, initiate the squat from your hips by sitting back and down, keeping the weight on your heels as opposed to the balls of your feet. Squat down to a position where your thighs are approximately parallel to the ground, then press back up to the starting position. Keeping your weight more towards your heels is the key factor in squatting to protect your knees from injury and develop strong injury-resistant knee joints. Keep in mind - squats done correctly actually strengthen the knees; squats done incorrectly can damage the knees.

Practice first with an un-weighted bar or a relatively light weight to learn the movement. Most people are surprised how hard this exercise works your abs once you learn the correct form. This is due to the more upright posture compared with back squats. To see photos of proper form on the front squat, visit http://truthaboutabs.com/Front-Squats.html.
