This wont help with muscle ups (you should just work on ring muscle ups or go outside for those) but it is a great doorway pullup bar and you can do dips too. The bar is raised up higher than usual, which is nice, and the dip attachment makes it a winner. I had it and liked it before i got my garage pullup setup. https://www.amazon.com/Triple-Door-Ultimate-Doorway-Trainer/dp/B0093T6R4C/ref=cm_cr_arp_d_product_top?ie=UTF8 80 bucks and youre in!
