Re: Exercise: Daily vs. Every other Day
The less time you have between sessions the less time you have to recover. The more effort / strength you use in a session the more rest period you need to repair your muscles and for to allow them to grow. Your strength gains really have nothing to do with the frequency of the exercise. Your strength gains are a result of your body having to lift a weight that it not use to and then allowing it enough time before the next session to recover and grow.
The difference between doing an exercise daily compared to every other day or longer, is your body will have less time to adapt. So the sessions will become more aerobic and cardio than muscle and strength building. You also increase the risk of injury if you perform strength training too often without adequate rest periods.
When you talking about strength training there is a very simply rule to know how often you should train. You should be as strong if not stronger in every training session you do. If you find your not, then your training too often and need to increase rest periods. As you become stronger and the intensity increases you will find that you need to reduce your frequency. I train now aprox every 5 to 7 days. Although when I started I was training 4 times a week.
