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.
Stretching your psoas muscle lying down can be done on the floor, but it works best on the edge of a training table or bed. Lie on your back toward the lower end of a table so that your buttocks is at the edge. Allow one leg to hang off the edge as you grab the other knee with both hands.
The Fix. Psoas Stretch: Keep hips under ribs, shift the knee forward and sink the hips down as the body moves forward. Rectus Femoris Stretch: Sit back and gently reach your hands behind to the bench for support. Tuck your pelvis under to avoid excessive arch in your lower back. Extend your hips forward and feel the stretch in the front of your thigh. Rectus Femoris Release: Hold the top of your thigh on the roller when you feel the painful area. Keep it on for 30 seconds, then roll down and out to find more spots. Repeat four times. Barbell Hip Raise: Push your heels into the floor, brace your core and squeeze your glutes as your hips rise.
