1x/week is garbage. You need more frequency than that, cycle or no.
There are a million and one ways to set up training with higher frequency. A push/pull setup is a pretty good example. Something like:
Mon - push 'a':
Squat (straight sets, like 5x5, 3x8 or whatever), bench, inc. dbs, maybe some triceps stuff
Tues - pull 'a':
Rows, chins, power shrugs, biceps stuff
Thurs - push 'b':
Front squat, standing overhead press, weighted dips, triceps stuff
Fri - pull 'b':
Deads/GMs/RDLs (pick one), rows, pullups, biceps stuff
And of course you can overtrain on a cycle. Steroids aren't magic. The body recovers much more quickly while 'on' but is not immune to fatigue.
