paul thats cause your starting out though, thats ALL the muscles growing, small ones and big ones aswel as the joints getting used to it, give it 3 weeks then the normal gorwning pains will appear

when i first started out at the gym i couldnt straighten my arms due to the pain, i was lifting 25 litre drums of oil to stretch my arms as i needed to streach for it to heal qqucker !!!

these days i get pains but not for a few days like the first time, just sometimes im tight in the morning and need to get my heart rate up to loosen up,,,, its cool cause my little girl loves doing star jumps before school with daddy !!!
