No more than sixty seconds rest should be taken between most exercises. Even better results will take place if the rest periods are reduced to thirty seconds or less. On some exercise cycles like super sets and pre-exhaustion sets, it is necessary that you move from one exercise to the next in less than three seconds.
Two favorable things occur when you move quickly between exercises. First, your heart rate stays at a higher level. Such sustained heart rates lead to improvements in your cardio system, which is a big PLUS. Second, moving quickly between exercises means you'll have to reduce slightly the amount of weight you handle on each exercise. Even though you reduce the weight, it will feel the same to your involved muscles, and it will have the same effect as resting and using heavier weights.

BENEFITS of REM and Non-Rem SLEEP !!
sleep, health, fitness, muscle, dream

Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep, which consists of 4 Stages.
When you sleep, your body rests and restores its energy levels. Sleep is an active state that affects both your physical and mental well-being. A good nights sleep is often the best way to help you cope with stress, solve problems, or recover from illness.
During the deep stages of NREM sleep, the body repairs and regenerates tissues, builds bone and muscle, and appears to strengthen the immune system. As you get older, you sleep more lightly and get less deep sleep.
Usually, REM sleep occurs 90 minutes after sleep onset. The first period of REM typically lasts 10 minutes, with each recurring REM stage lengthening, and the final one may last up to an hour. In people without sleep disorders, heart rate and respiration speed up and become erratic during REM sleep. During this stage the eyes move rapidly in different directions.
Intense DREAMING occurs during REM sleep as a result of heightened brain activity, but paralysis occurs simultaneously in the major voluntary muscle groups. REM is a mixture of encephalic (brain) states of excitement and muscular immobility. For this reason, it is sometimes called PARADOXICAL SLEEP.
