Another routine that worked out quite nicely for me, highly flexible also.
Staring off set yourself a shuttle running layout – please comment if you are unaware of what this is. Second layout is a pool of footballs
Split your group into 2 teams one with bibs, start with having one team attack vs defence. In order to keep the intensity of the routine up ensure the pool of footballs is accessed immediately once the active ball leaves the pitch. When you run out of footballs get the 2 teams to go and start the shuttle running, afterwards switch the attacking team to defending and vice versa – once completed do another set of shuttle runs.
The ideal outcome to this is to develop an intensity to the playing, along with improving a level of fitness.
