I’m doing the first progression of exercises and it’s not very hard, thus I’m doing all the exercises everyday except the handstand thing which I will start only after I can progress to level two with all the others.
I’m mixing it up with the reps so some days, I do 2×25 some days 1×40 and so on increasing gradually. If I’m tired I break it into two sets, otherwise I do all reps in a row, keeping the total reps more or less same, occasionally bumping up that number by 10.
I try never to push forward if I experience a "bad" pain.
Knee tucks however, I am not able to do more than about 15 in a row without experiencing pain in the lower back. I often start out thinking I’ll do 2×25, but the pain starts at about 10 reps and so I never push beyond 15.
I’ve done all sorts of ab exercises in the past and not had any back pain – I also used to do back raises regularly(on flat ground), so I don’t know why my back complains now.
I have no problem doing the short bridges (my last two workouts I did 2×30 and 1×40).
Shoulder stand squats too cause me an ache in the lower back after about 30 reps or so – However I support my back with the arms, I’m not able to hold the whole body in a vertical line and the lower back starts aching…
What should I do?
