Best Extender for uncircumsized

Hey all,

I’ve been doing JP90 off and on for 2 months but am just really finding it hard to fully commit to 1.5 hours a day 5 days a week when I need to work. An extender would let me train while I work so that’s what I’m hoping to do but I am not cut so would love some advice from anyone whose in the same boat and using an extender as to which works well for us!
