Down to 1

For the pause pistols (single leg squats). Use a target and pause touching the target. Try your best not to plop onto it, but just briefly pause.

For this movement you really have to reach your butt back and try not to allow the knee to roll in with the heel down!

The side lunges are actually very similar. You will hold a KB, DB or Plate at the chest. Reach to the side and into that one leg. Reach the butt back and down.
