If you don't have a sturdy coffee table, do alternating forward lunges instead.
- Stand in front of your sturdy coffee table.
- Step up with the right foot, then the left, bringing both feet completely onto the bench.
- To return to the starting position, lead with the right foot to step down to the floor, then the left, until ending with both feet on the ground.
- Complete 10 reps on this side, then switch legs and start stepping with the left foot for another 10 reps.
