Fitness challenge workouts are widespread and common in today’s fitness world. With people having an increased desire not only for physical fitness, but for improved health of their bodies, more time and effort is being spent towards those goals. However, with the seemingly endless increased time demands of family and work, the time demand of exercise gets squeezed.
Fitness challenge workouts attempt to burn as many calories as possible into as little time as possible and yet also satisfy the need of exercising many different muscle groups. All muscles contain glycogen which is the energy source powering the movement of the muscles.
As the many different muscle groups operate independently of one another, an exercise involving one muscle can be completed and thus fatiguing that muscle without affecting another muscle. This allows for the individual to immediately begin and second exercise which involves a completely different muscle without a rest period for the first muscle.
The purpose of rest after any exercise is to allow for lactic acid to leave that muscle. Lactic acid is formed as a by-product of glycogen being used as energy without oxygen. As the glycogen is used, lactic acid builds up and causes a burning sensation. More importantly though is that lactic acid build-up is the body’s defense mechanism against the muscle being damaged by being overworked.
Squats: It can be performed which will exercise the hamstrings which are the muscles on the back of the upper leg when squatting down, and the gluteal muscles which are the muscles of the rear end and one of the four muscles of the quadriceps, which are the muscles on the front of the thigh when standing up.
Push-ups: After performing a set of squats, the individual can immediately move on to Pushups, which use the muscles of the chest, shoulders, and triceps. While rest is required for the legs and glutes, the rest period occurs while these muscles are being exercised.
Sit-ups: It can be performed after the push-ups which will engage the muscles of the abdomen. In all, seven different muscle groups will have been worked in a minimum of time. This rotation of exercises can be repeated several times to the extent the exerciser wishes to work and burn additional calories.
