Hi guys, needs some insights. I apologize if I posted this is the wrong section.
I've been follow coach's F1 and it's being effective. Though now I'm slowly transiting to other positions from coach's book, Gymnastic Bodies. Last week was my first week after I changed my routine from F1 to my own (which is still the same as F1, just different position using coach's book). I notice that when I do the FL tuck, my shoulders strains a lot and there's some level of muscle pain, as if it's at it's limit. I tried aiming for a 24 seconds hold today but after 15 seconds the pain comes. Is it normal because my strength is not yet a the level to fully support the FL tuck?
