Thanks for the recommendation, but is it possible to do something for the back without a bar to do the pullups? I dont have a bar and I cant install one on the apartment I rent. Thanks!
If your doors are sturdy, make a knot in a towel, hang it over the door and close it. Use that to do pullups. I used to do this a lot during traveling.
You can also do inverted rows under a table by holding on to an edge (not comfortable, but works).
You could invest into a dumbbell and/or resistance bands and do row variations. Or a TRX for inverted rows.
Or go to a park or anywhere else where you can hang onto to do your pullups.
They're a little low and only support <250lbs, but otherwise they are perfectly fine for the average home workout.
