Guys who said that You cant lift with the same muscle until 2 days after the last time u lifted meaning if you lift chest on Monday you cant do it until thursday.
As Jungledoc noted, if you lift on Monday, then you should be able lift on Wednesday.
Can someone please tell me if you can have a lower resting time
Recover can be enhanced (you can "have a lower resting time") but only to a point. How quickly you recovery is dependent on a number of factors (Stu made mentioned).
and why is it 2 days?
Becasue there is a correlation between time and the healing process. Clarance Bass presented some research on this in one of his books. The reseach is more like common sense.
"The greater the trama to the body, the longer it takes to recover."
It like Stu stated, "The time between lifting is dependent on how intense your last training day was."
Think of it like breaking your arm. Can you speed up how fast your broken arm mends. If so, how much faster?
Stu also mentioned a chart on it. Stu may be referring to Dr Fred Hatfield's chart. How quickly one recovered was based on factors such.
1) Age (Younger lifters reover faster than older ones).
2) Training Age (How long one has been training). The more years you have been training the longer it takes to recover.
3) Lifter's Size (Larger lifters take longer to recover than lighter lifters)
4) Muscle Size (Larger muscle such as the legs take longer to recover than smaller muscles such as the biceps).
I can't remember the rest of the list.
Better yet, try pushing your max seven day a week in on exercise and see how that works for you.
