Gymbar Iron

My door frame hasn't budged, even with me doing explosive kipping pull-ups, and the foam padding is actually grippy enough to hold without slipping.

Installed it in under a minute and did my first set of pull-ups right away. The rubber grips keep my hands from slipping even when I'm sweaty.

I was surprised by how sturdy this feels once it's wedged into the doorframe — no screws, no damage, and it holds my full weight without shifting.
