Why do I like single-leg deadlifts so much? Because they help low back pain! I used to be a figure skater, and I had low back pain I needed to rehab over the years. These helped me so much! The single-leg deadlift is simple and effective. It helps with preventing and rehabbing low back pain, as well as improving balance. You can do this with a kettlebell or dumbbell, and I would suggest that beginners can do it without any weights and still get effective exercise.
