Hello I am 25 and am currently very unfit. I played footy up until I was 20 and was quite fit and fast, and have done weights training on and off also. I tried to come back and play rugby last year and had terrible trouble with shin splints... I think - excruciating pain on inner side of shin bone and in calf. At the time, and now, I cant break into full sprint. I push as hard as I can but my body won't go to the extra level. I'm playing touch footy at the moment and after a couple of minutes my legs feel like the weigh a ton. I have also had bad back problems over the last 2 years. Can anyone suggest any training to get my legs back?
