Also beginning with this plan. For the ice tools max hang benchmark. What does it mean with “engage the shoulders about halfway between fully slacked and fully engaged”? Should my arms be straight or slightly bent? If I start hanging with straight arms fully slacked and then tense the arms slightly as If trying to do a pullup (but arms still straight or almost straight) I can easily use 40-45kg without losing the grip in 7sec. on the other hand If I instead hang with tense biceps slightly bent arms my max is 10-15 kg or so. so big difference.
