Hope it helps I can only manage 5 strict chest to bars now where before i was at 2 and 3. Not great but my overall "normal" pullup numbers have gone up from focusing on these.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
