Is rest day necessary if muscle is not sore?
For example, can I train upper body and core 5 days in a row? (Which i am doing now)
I have practiced bodyweight training for sometime, therefore my recovery speed is quite fast I think.
Suppose all reps are executed with high quality, by doing more sets like 10 sets of RCPE1, or have 6 days a week of RCPE1, can I say I will have more improvement?
