How about this:
Monday-Friday: Lift weights in the morning (lower body on M/W, upper body on T/T, everything else on Friday), train muay thai at night
Sat/Sun: Rest
There's a reason God made man rest at least one day a week.
Learn to understand your body. It may sound Zen-ish, but if you're feeling overly fatigued, then know that's your body giving you the okay to rest. Don't feel guilty or lazy about it: you pushed yourself all week, why destroy your body?
Break it down to build it up. But don't raze it to the ground.
God was made by man. Just like the santa clause
Is it ok to train muay thai everyday without overtraining? If not, what do they do over in Thailand, because it looks like they train everyday in their muay thai camps.
