Dear FF members, I'm used to playing 6 - a side normally, I thought I would be fine in a 11 a side. I recently started playing 11 a side in Sunday league (CDM/CM). Recently I was in the starting 11, I was on for 20 mins, came off because I was out of breath and energy! No Stamina. In order to build up stamina and continue running I thought I would do jogging outside football. However there's massive difference when I'm jogging with boots on grass and jogging with trainers on road. In order to improve my stamina and last longer on the pitch. Is it better to jog on grass pitch with my football boots, or is it better to jog on the road? Experience and advice would be much appreciated!
