I started working out with Jim at Silverback last summer and it was one of the best things for me as an athlete. Not only were my numbers in the gym going up every week but I was becoming stronger and harder to play against on the ice. I would really recommend working out with Jim for anyone who wants to become a better athlete, healthier person, or put on some muscle.

Jim is a kind and welcoming person and I feel safe during our workouts. He takes time to understand what I want to train and adapted our workouts. Jim also takes time during the week to plan something new every time and he always makes sure I understand the moves.
