Hi coaches,
I ve been strugling with this exercise for around 4 months or more already. I know it sounds crazy, but very recently I realized it was probably due to lack of mobility. I was always feeling lower back discomfort or even pain much earlier my abs would give up and didn t seem to get any better. Reading the forum I came to the conclusion could be lack oh hamstring and hip flexors flexibility. So last time I worked out this I strechted those before and didn t feel any discomfort! I hope i ll progress faster now. Is my form ok? Thanks.
