  • “10/10 would recommend Swain Performance because Jack not only knows a variety of workouts, but the mechanics of body and the “why” behind the programs. He’s a thoughtful trainer who adapts his programs over time to achieve new goals.”

  • “I was a little skeptical about coming to Swain Performance at first because I had gone to a gym less than 10 times in my life before starting...I keep coming back because it is a private place to workout…1 on 1 training with immediate guidance and support.”
