Re:Anyone else get a clunking noise when they do situps?
I have this same problem. I've been trying to work out why it does click for ages. The thing is i get slight lower back pain when i heavy squat. I also get it slightly when i deadlift, but since i've improved my form it hasn't been that bad. If you get any pain is it like the lower part of your back i.e, just above you glutes? I'm not sure how to fix this, but it has improved and hasn't got worse. I've been looking at whether it's some muscle like gluteus minimus and doing some stretches seems to help. I hear the crunches also when i do situps and wondered if this is the reason for why my back pain got worse and certain stages of training.
