Let’s talk Pull Ups!

CrossFit gets a bad rep for crazy pull ups. But we ado work on our pull up strength.

Working on pull ups looks differently for our athletes. Some can go faster, some slower. Some use a band or do jumping pull ups or grab some rings for ring rows. The goal is to get stronger each day!.

Come in and let’s get stronger together!

I have been trying to model my reps after and what you see him doing is reps done with absolute intention. There is tension and control visible in every rep when he lifts. He never sacrifices weight for control.

I’m doing low incline press with lots of control for 10 sets of 10 and trying to not just toss around the weight without intention.

The saga of chasing perfection continues and we will stay at it all summer during prep; I am five weeks out from starting working on my build for in September again!!
