This monster doing kneebends at the Monster Gymnasium.

Up! Down! Up! Down! Work those glutes! Work those hamstrings! Up! Down!

Exercise is hard work but makes you a stronger monster.

That animation wasn't available just now, so we are showing you THIS one instead! Enjoy.

This particular animation requires some technology that won't work on your itty-bitty phone!

Not to worry though. Watch some Youtube animations instead.
