Choose the mounting type first. Then check the exact product's fit, load rating and instructions. You do not need a basket of accessories to start a training log.

What can your space support?
Doorway bars
Consider this if: You need a removable setup and have a compatible door frame.
Before buying: Measure the opening and frame profile. Check the exact mounting instructions, load rating and permitted exercises before ordering.
No-drill does not mean every doorway is suitable. Product requirements differ.
Check the instructions, not just the listing photo
Different mounting systems have different requirements. Rogue's Jammer installation guide specifies a standard wood-stud wall. Decathlon publishes separate guidance for its doorway products. One product's installation rules should not be applied to another bar.
These shopping links currently use Amazon UK. Check delivery to your country and any charges before ordering. You can use the mounting checklist with a local retailer; this site does not currently offer a verified US shopping route.
Ready to use the setup?
Use the same bar and grip when comparing holds. Record assisted and unassisted hangs separately so a change of setup does not look like a change in performance.
