Ok here's my list of good times, will break it into sections for you...

Whole body

Burpees- My favourite body weight exercise around, you should do these in 2 min intervals with the number of them being the number or rounds you fight + 1. Stand there arms by your side, crouch down like doing a bodyweight squat while putting your hands on the ground shoulder width apart and infront of your knees. Kick you legs out, while lowering yourself into the push up position (close to ground aka have to pushup). Do the pushup then return your legs to the crouch position and explode up doing a tuck jump. That my freinds is a burpee and the ulitmate in intesity workouts.

Chair lift- sit on a wide chair, place your hands on the edge of the chair next to your legs. Lift yourself off the chair and stretch your legs out straight and hold.

Superman- Like the one mentioned above, get in plank position, raise one leg off the floor and opposite arm and hold. Intensify this by a stupid level by doing the suspension bridge and doing this. But do not do that unless you have a great core strength already.

Have to go shopping now so next installment will be upper body madness
