Lateral crab walk
Tips from Peter:
Place a resistance band, loop or hip halo just above the knees
Start your knees shoulder-width apart, perform a short squat and hold this position whilst walking side to side
Lead with the foot and knees and try to avoid your knees drifting together as you take a step (knee valgus) to really work your glute muscles.
This is a widely used strengthening exercise for your gluteal and hip muscles and is a common rehab exercise for a lot of lower limb conditions too.
