I was wondering if you have any suggestions for modifications if you don’t have a bar? I can jump without holding on, but, as an example, bar pull-ups and other similar moves. Thank you!

Great question! Pull-ups are definitely a unique maneuver that requires a fixed bar above your head. Depending on what other maneuvers you've done during your workout, you swap in other upper body exercises like a military press, bicep curls, push-ups. If you incorporate elastic bands, then you do some pulling exercises that, though not exactly the same, can work similar muscles. Hope that helps!
