Kinetic energy is produced. The energy your muscles use is chemical energy, which is gotten by food. The muscles do an action, therefore giving off kinetic energy.
strength activity!!!!!!!!=)
Endurance type activities

heat energy
Energy is stored as fat in the muscles.
flexibility activity A+
Lower intensity activity in fact does very little for muscle preservation. You want to increase exercies intensities because intense exercise activates more muscle mass, this type of activity can help in building and preserving muscle as we age.
Strength and power exercise like weight lifting requires the explosive release of energy yielded by fast-twitch muscle fibers. Slow-twitch muscles are involved in endurance activity.
Cells that do a lot of work or activity such as muscle cells.
