Looking to blast the legs? Get a rock solid butt?
Do a few rounds of these and I promise you will be shaking!
Start by standing behind a bench.
1) With the right leg back perform a low lunge.
2) The right leg swings forward without touching the ground and steps onto a bench.
3) Bring yourself to a complete standing position on the right leg on the bench.
4) THe left knee drives up into a high knee while on the bench.
5) Repeat 5-10 times on one side, and then switch the leg that is lunging/stepping up.
The picture below breaks it down for you:
