im doing it like circuit-training:
today i made:
3Rsquats-3Rbenchpress-3Rchins-3Rsquats-3Rbenchpress-3Rchins-3Rsquats... till i finish 30R for every movement.
after that i did:
3Rdeadlift-3RDips-3Rmilit.press...
this way it saves time and you get a lot of TUT without fatiguing your CNS.
metabolic stress is no big factor for hypertrophy - but a small one.
im handling it like that: in the first weeks i have no need for clustering - high reps are causing enough metabolic stress for me.
later in my cycle i start clustering. my only goal is to have a long TUT with the heavy weight...
