Coaches can really speed up your progress in the gym – they give you feedback on your form and advice on corrective action – even if it’s in the form of a watch. The GymWatch measures the full range of motion and strength expended in training and coaches you to get the most out of the workout. It can come up with a personalized exercise plan to get you to your goals quickly based on the measurements for strength, maximum strength, explosive strength, speed strength, amplitude and the number of reps.
