Check out a thread by Bowelzilla at www.gearnutrition.com he had info about box squats on a germanvolume training schedule. Might be just what your looking for.
What is the point of a light workout? Other than MAYBE helping to pump blood into the muscles....if you're working out 'light,' you're not building muscle, and if you're not building muscle, why the fuck are you in the gym?
how many sets are you doing ? Also ...just drop the thursday workout ...all it is doing is impinging on your recovery ability...and doing nothing for growth.....do not train lower back 2 times a week! you are asking for an injury....only do it once a week ....only deadlift hard once every 10-14 days .....check out the routines of world class powerlifters they only work lower back once every 10-14 days ....
No. Make your workouts short and intense, they can be longer if you are on gear. Work your muscles so hard, heavy and intensely that you NEED that full week to recover..remember, it's not just your muscles, it's your nervous system that must recover as well.
