In this Mani Reacts episode I look at the whole “grip strength training” hype that’s floating around climbing right now, and I give you my honest take: most of what these grip gadgets measure is strength in the palm/first knuckle area, and that’s basically irrelevant for hard climbing. In climbing, what matters is whether you can transfer force into the fingertips—on small edges, shallow pockets, and all the annoying little limestone bites. Same reason I always say: a one-arm pull-up on a bar is whatever; doing it on a 10mm edge is the thing that actually transfers. I react to Magnus Midtbø testing grip tools with Adam Ondra and use it as a springboard to talk about what’s actually climbing-relevant: finger strength vs “grip strength,” how cupping a hold changes force distribution, and why pinching in climbing is often about friction and position (not just squeezing). We also get into genetics and morphology (short fingers vs long fingers, fat vs thin), the isometric “locking” nature of climbing, muscle memory and why projecting works, plus left-right imbalances that gym climbing can create. And at the end I answer the big question: if grip strength monsters are so strong, why aren’t they dominating rock climbing?
