Should You Be Doing These Workouts??

By Trevor Johnson


Have you ever taken a look around your gymnasium to see what the people around you are doing?

Do you question if the workout they are doing will help you accomplish your own physical goals quicker?

Those are a small number of inquiries to ponder as you continue reading this, but the fact of the matter is there is almost always a 'better ' lift to do than most of the lifts that you see people performing at your gymnasium.

For example, today a couple in my gym took it upon themselves to do a selection of exercises working their body from head to toe, or that's what they believed.

Their workout commenced with some dumbbell shoulder shrugs. That exercise targets the trapezius muscles that, if massive enough, might make you appear like you've got no neck.

On the surface of things that would appear to be a handy exercise to do, but if you dig a little deeper you'll find that exercise does little in the way of helping you burn even the most minute of calories.

Let us look at it mathematically. The amount of work done equals the force times the distance you are moving that force and the amount of times you are moving that force. As an example, if one was to use 30-pound dumbbells you might move that weight a sum total of three inches maximum. The trapezius muscles aren't that large so don't have the range that the bigger muscle groupings do.

So that 30-pound weight moved 3 inches, 10 times, gives us a considerable number of 900. The unit of measure at about that point is irrelevant.

Now lets take a look at an alternative exercise, the army press. This exercising is done with an Olympic bar pressing it from about your chin all of the way above your head until your arms about fully extended.

For this exercise we only used the weight of the bar which is 45-pounds. If you make the motion as if you were performing the exercise you might notice that the distance that bar is going to go is around twenty-four inches or more depending on your size, and that was done for a total of ten repetitions. So 45-pounds, times 24-inches, times ten repetitions gives us a number of 10,800- again the unit of measure is irrelevant. It only becomes relevant if we were to calculate that number into calories burned.

On the surface, doing the military press was 12 times more effective than doing a dumbbell shrug, and that was with only the 45-pound bar.

This is only one example of one way to see if you are getting the best out of your workout session. Many of us are unconcerned to a couple of the exercises that they decide to do and just do anything that comes to mind. You only have so much energy when you hit the gym floor, make it count and put it toward exercises that will give you the bang for you buck.
