Right ladies and gents I knew that getting fit would be painful i expected nothing less. When im out running (jogging/fast walk by your standards) for the first 10-15 minutes im experiencing incredible pain in my right leg, focused just under the knee. It doesnt feel like muscle pain its like someone is kicking the front of my leg everytime i put my foot down. I have tried resting it for a couple of days then went back to the gym no change, i have noticed bruising beginning to form just under my knee on the inside of on my right leg and the same on my left leg. Im certain I havent hid my legs on anything to cause this. Anyone know why this is happening? and is it normal for the er larger man. At the moment im just tolerating it and carrying on, I need to get the run time down more by the end of November and as such dont really want to stop. On the plus side ive gone down from a fat man 40" waist to a 36 inch waist, nailed the press ups and sit ups and love doing fartleks and running.
