Great way to firm the thighs!

Yes, monsters can be done going forward or side ways. Also, another variation is to do side steps, knees locked.

It is really important to get either one on one or group instruction with these exercises. Form and technique are important, and let me tell you some of the exercises were tough to learn.

Here is a list of some of them:

Sidesteps: w/band knees locked
Monster Walk sideways
Single leg squat sequence
Single leg hamstring curl using gym ball
Gym Ball Squat, ball against wall
Static Lung with Theraband
Hamstring curls, gym ball w/ both legs
Lateral step downs
Lateral lunge with reach
Zig Zag Monster Walk
Sidelying clams
