I love the climb this guy does - so much strength! but it's not really in straddle position. I've heard it's possible to do an arms only climb with legs in straddle position and would love to see how its done.
If you sit on the ground with legs either side of the pole in straddle position, pull up off the ground then you need to start moving one hand at a time to pull up. It's hard, you need great arm strength, good momentum and pace.
