Complete a two handed kettlebell Clean & Press, set kettlebells on floor by feet, walk out on your hands, do a push up, walk back up, repeat. Killer!
I used a modified version of this tonight as part of a circuit.
I did a dumbbell snatch with the left hand followed by one with the right, then walked the hands out to a plank, did a pushup and walked the hands back. Did 10 reps, then 10 "slasher to halos" then 3 flights of stairs carrying a 25kg plate. Then repeated the whole circuit.
