for the longest I thought chin ups were pull ups… BIG DIFFERENCE. lol the grip changes which muscles are more engaged. underhand for chin ups utilize your arms along with lats while pull ups, and mostly lat focused or at least thats what I gather from all the fitness gurus lol. working to be able to hit 10 of these clean by the end of summer! #gymgirlie #gymlife #oneractive #planetfitness #pullup now you tell me which is easier? ↓
