Getting fit in the great outdoors, surrounded by a lush cool forest, is fantastic. Everyone should exercise this way. Give that smelly old gym the flick and try it for yourself. The program is personalised even though you are in a group, but at the same time you are constantly challenged. I also do kick-boxing with LIFE FORCE, but it's not outdoors. Even so, it's great fun whilst getting fit at the same time. I have been training with this group for nearly four years now. I highly recommend it.
