Highly recommended. Having the ability to transform most dumbbells, barbells, chinning bars, cable machines etc into thick grip bars is awesome! Makes training so much more fun and challenging. My only negative (hence the drop in one star) and its a small one... if doing high reps on dumbbell curls for example, the rubber material of the Fat Grip can occasionally cause friction burns as the fat grip rubs against your skin during exercise which can be annoying. But definitely NOT a deal breaker.
