Most clients have logged hours exercising on a conventional gym machine (ab crunch machines, tricep extension, shoulder presses, knee extension, abduction/ adduction machine). Looks like they get a great “pump”, but what are they really working?
Muscle recruitment on exercise machines
Your nervous system only activates the muscles in direct relation to demand. The machine only challenges the outer units, which are the bigger muscles designed to move your limbs, with very little activation of your stabilizer muscles.
Consequences of exercise machines
You will strengthen your outer units while your stabilizers remain dormant. This leads to undertrained stabilizers, and when you decide to do real life tasks, such as lifting up a box or picking up your squirming toddler, your structurally imbalanced body will fail, risking injuries.
