If you try to go hard all the time, you'll likely suffer more serious problems too recurring injury and illness, sudden weight loss, and fitful sleep are all signs of overtraining. If any of this stuff arises, then take it as a signal you need rest. Exercise physiologist Sal Blau recommends a simple test to see if your body is being overstressed. Each morning before you get out of bed, count your pulse beats for a minute. That's your resting heart rate.
Rest is equally important in weight training too.
You may want a ripped physique, but you're not going to get it by training like Arnold Schwarzenneger on amphetamines. Weight training produces microscopic tears in the muscle. Taking at least a day off between lifting sessions gives those tears time to heal, and the muscles time to grow. It's really exquisitely simple. Work Outdoors at GORP Jobs Click Here.
