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 do?

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

Those are a number of questions to contemplate as you continue reading this, but the fact of the situation is there is almost always a 'better ' lift to do than the majority of the lifts that you see people performing at your gymnasium.

For example, today a couple in my private gymnasium took it upon themselves to do a variety of exercises working their body from head to toe, or that is what they assumed.

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

On the surface of things that would seem 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 quantity of work done equals the force times the distance you are moving that force and the amount of times that you are moving that force. For example, if one was to use 30-pound dumbbells you might move that weight a total of three inches maximum. The trapezius muscles aren't that massive thus do not have the range the larger muscle groupings do.

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

Now let's have a look at an alternative exercise, the military press. This exercise is done with an Olympic bar pressing it from about your jaw all the way above your head till your arms about absolutely extended.

For this exercise we only utilised 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 24 inches or even more dependent on your size, which was done for an overall total of ten repetitions. So 45-pounds, times 24-inches, times 10 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 twelve times more effective than doing a dumbbell shrug, and that was with only the 45-pound bar.

This is one example of one way to see if you're getting the best out of your exercise session. Many of us are insensible to a few of the exercises that they opt to do and just do anything that is evoked. You only have so much energy when you hit the gym floor, make it count and put it toward exercises which will give you the bang for you buck.
