| This is a rather funny looking exercise to do, so be prepared to get a few looks here and there when you do this exercise movement. Probably not the type of exercise you would want to do when the gym is really busy. Thus, considering the above stated, guys will most likely be better off doing this one at home. It's rare to see a guy doing this exercise at the gym. Another thing that's important to point out is that it's a good idea to do some warm-up and basic stretching before you do this exercise. Jumping right into it might cause you to hyperextend your back muscles if your back is not strong enough. Thus, it's always a good idea to do a few stretching exercises for 5 to 10 minutes before you start doing this core exercise. Finally, keep in mind that with this exercise, as with most exercises, it's important not to rush the movement. Take your time to execute it properly and try not to move your mid-section up and down by jerking your body using inertia rather than your core muscles. |
