Hi!
Having followed a strict routine of foundation in 3 1/2 month I can see some really good progress in both upper body and single leg squat programs. I have almost progressed through F1 entering F2.
The core is though very very hard for me and for example @4*48 sek of Straddle Hollow Body Hold I almost can not breath of almost cramping in the abdominals. (I am very strict with my form which offcourse makes it as tough as it goes but that should be a good thing)
I have been training in the gym for 30 years and I am a former martial artist with, what I thought, descent core strength BUT this has really humbled me ☺️
My body seems totally out of balance strength-wise, is this normal ?
Should I increas the number of core-sessions ?
