Mechanical Energy as the Ability to Do Work. An object that possesses mechanical energy is able to do work. In fact, mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy-whether it is in the form of potential energy or kinetic energy-is able to do work.s already mentioned, the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
A towel stretch is an effective way to stretch your psoas muscle. You can use a regular bath towel or a strap that's roughly the same length. To do the stretch, lie close to the edge of your bed on your stomach. Plant your outside foot on the floor and bend your other leg.
Lie on your back to stretch the gluteus maximus and hamstrings, which cooperate to extend your hip joints. Lift your left foot and bend your knee, drawing it toward your chest, and pull it closer with both hands. Hold the stretch for your desired amount of time, then switch legs. Kneel on one knee to stretch the hip flexors. Place your opposite foot on the floor in front of your body and flex the same knee to press your weight forward until you feel tension through the hip flexors of your back leg. Hold this position for 10 to 30 seconds, then switch legs. 1  Perform a low-intensity aerobic activity -- such as jogging, jumping rope or walking -- for five to 15 minutes to warm up before stretching.  Pay attention to your breathing as you hold each stretch and try to deepen the stretch slightly with each exhalation.
