he could use the bench rack for zercher squats I guess, they are the closest you will get to a real squat without an actual squat rack, and some higher rep front squats maybe with his powerclean 1RM.
Can he get a chinup bar?
He could follow something like
(this is pasted from another thread)
Session 1:
a. Standing overhead press: 5x5 a la 2 warmup sets and 3 hard fucking sets of 5. When you get all 3, move the weight up.
b. Standing curls: Do 5 sets of 5, just like above, supersetted with the presses. Maury did these and he was definitely not pussy, even though he got plenty.
c. Squats: 1-3 warmups then 1x20. Yes, these are breathing squats done with a weight you can only do 10 with. Trust me, you will be able to do this if you are not a pussy.
d. Stiff leg Dead: 2x15. Yes girls, this does hurt. But keep at it.
e. Ab work: Work it hard, don't be a _____. (fill in the fucking blank, numbnuts!)
Session 2:
a. Deadlifts: 5x5, see the guidelines above
b. Bench press or dips: 5x5, see above
c. Dumbbell Rows: 3x10-15
d. Chins: 3 sets for maximum reps. I know, too much back work...well, you need this much goddamn back work if you don't want to look like a pussy! Plus, chins help to decompress the spine after heavy lifting a bit.
e. Ab work...as above.
for the squats on workout 1, replace with some warmups then front squats with his clean 1RM which he will probably get around 20 reps with.
and he would do one of these workouts every 2-3 days, if the squats are too light or he cant powerclean enough or whatever, he could replace them with zercher squats from the benchpress rack 3x8 or something similar.
