home gym:

Pull up bar
Rings
Parallel bars if you can afford them
A chair

alright /fit/, im poor as fuck and need the best and most efficient equipment for the cheapest price to continue getting gains. i go to a uni gym and it gets unbelievably packed once the semester starts and i can't take it anymore.

what cheap home gym equipment do you recommend for a beginner? what are the essentials? (my budget is sub $300) picrel is what i'm maybe considering but i heard it's shit.
