Hello and nice to meet you. I'm 31 and two weeks ago joined a karate club. I haven't exercised in years and have no prior MA experience so I'm moving joints, ligaments and muscles in ways I'm not used to. I'm carrying a little bit of extra timber but I'm within normal range bmi wise. After my first class I experienced sore muscles, tight hamstrings etc which I expected. After my second I had a pain in my left hip when I reached the end of my range of movement which eased over a few days and now after my third the hip pain is back and i've picked up a pain in my groin. Im not pushing myself any harder than anyone else in the group and although previously I haven't exercised in my free time I've always been active through my job (plumber) so I didn't expect to feel so fragile. I'm wondering whether its normal to experience these kinds of aches and pains and whether through more time and karate training they'll stop? Also are there any exercises any one can recommend which will help build up strength in the hip muscles? I've been doing a bit of core work like sit ups, leg lifts and planks. I'm not sure if I'm doing more harm than good but the last thing I want to do is stop training to heal when I've just started. It took an early mid life crisis to get off my backside and into a dojo, I'd really like to find a way to work through it. Maybe I'd benefit from some weight training? Thank you for reading if you can help and thanks for the great forum. It's a great little resource.
