Start standing up on a slightly elevated surface (1-2" max, I am using a plate!) Engage your core for balance as you slowly step back into a reverse lunge, and press through the heel of your front foot as you stand back up. Do all on one side or alternating.

Weight Recommendations:
Beginner: Try just the bar first or dumbbells

Intermediate: 15-35lb plates on each side of the barbell
Advanced: 40-60+lb plates on each side of the barbell

*Modification: remove the elevation and do them with any type of weights.
