Soreness is wat i'm feeling

Last week was a hectic week , went for jogging on monday , karate training on tuesday , jogging again on wenesday , training again on thursday , went out on friday and played futsal on sunday. All these not including the weight training i did. Man, i think my body is still trying to adapt to my sudden hectic schedule. After enjoying 5 weeks of holidays i seem to have lost bit of fitness, although i do jog during the holidays, but not much... probably around once a week. I must have eaten a lot during holidays and didn't really balance it with exercise. Somehow my abs is like getting fatty . Man it's driving me nutz when i look at it. It used to look like this as seen in the pic below. Although not great but now it's worst. Think i gotta be more disipline and do like a hundred sit ups a day ...AT LEAST. I do take snapshots of meself once in a while just to keep track of meself. It's more like a self-reference rather than vain or watever crap dat u can think of. It's good for me to know the areas for improvement rather than asking some other people to check for me...lolz...
Today's training was great although my legs wasnt functioning well at all. Shihan(higher rank than Sensei) gave a lot of tips on ways to improve. It was really enlightening , juz hope i can remember all the important points. To think of it, the analysis of a punch and a kick still goes back to Newton's law. F = ma With mass constant it all depends on the burst of acceleration. There's where you generate a lot of force even though ur not the biggest person in the world. For instance.. Bruce Lee is actually quite small size but he's well capable of sending the sand bag hitting the ceiling when he does a side kick. If only he was alive, with all the new technology today it would be really interesting to find out how much force he can generate. Unfortunately, he died early but he's memories will remain as long as there's martial artists....
