[PrideR]

22y 150lbs 10%bodyfat
been lifting for 2 years now
3 day split basic compond movements high intensity, low volume ( i'm an ectomorph )
Last 8 weeks i used hst and gained alot of strength, but no mass.
Now i wanna change my routine. My recovery is great so i wanna try this 6 weeks:

first week:
monday: chest shoulders triceps
tuesday: back biceps traps
wednesday: legs, abs , calves
thursday: monday workout
friday:tuesday workout

second week:
monday: chest shoulders triceps
tuesday: back biceps traps
wednesday: legs, abs , calves
thursday: tuesday workout
friday:wednesday workout
and so on.
30-35 minutes workout; 2 exercises per bodypart ; only compound
its that much ?
