As part of the August Fit Challenge we need to post a new exercise.
This is my favourite new exercise that Tim showed me a few weeks ago.
Its fantastic. It doesn't feel like much but trust me, lay down, lift up your arms and legs and don't let them touch the ground again, and rock back and forwards. The pain is amazing.
Give it a go and let me know how many reps you made on your first attempt. Its a painful yet addictive exercise.
