First I must say how much I love the Im's for HBP in F3-F4. I've been having some issues with my right shoulder since May and just after a couple of times trying all the new Im's it feels alot better. Maybe it's just a coincidence but I hope not.
Back to Cubans. I've used these for years and and like them alot.
What are youre thoughts on these?
How heavy should we go on these? End goal 1/3 of our body weight ? More less?
Should one realy focus on retracting shoulder blades or just stay nutural?
