Chin-up bar ab strap attachments add another dimension to your core workout. Attach to any standard chin-up bar to isolate and challenge major core muscle groups including lower obliques during leg lift exercises. Comfort straps lend to longer sets and more gains while enhanced durability ensures years of workouts. The Ab Straps can transform your at-home pull-up bar into a more dynamic training station, and provide a more complete workout without taking up more space in your garage, basement, or wherever your home gym is.
