Started training with Marc approximately a month ago. I am a senior with heart issues, and Marc has adjusted my workout to match me and my condition. He is a very positive, encouraging trainer. I enjoy the programming he set forth for my workouts. I get my cardio through lifting, muscle-building exercise, which I really enjoy. Always on time, workouts are smooth and planned, and he keeps things planned ahead. We do training to trigger different muscle groups to work the way they should. He has a good understanding of what muscles and what exercise make them work. Pleasure to work with.
