It’s Day 12 of the challenge, and we’re focusing on the inner thighs in this 25-minute strength workout. Keep the mind-to-muscle connection top of mind as you work through moves like sumo squats, deadlifts, lateral lunges, and more for 45 seconds each before ending in a burner. All exercises are performed standing, so there's no need for a soft surface if you don’t have one handy!

Equipment: 10lb Dumbbells
