Best Overall Workout: X-Force at Main Line Health & Fitness

When Roger Schwab promises results, he delivers them. The veteran fitness pro and owner of Main Line Health & Fitness believes that X-Force training challenges his members in ways that produce amazing outcomes. X-Force looks similar to other machines, but your muscles immediately feel the difference. Ask Schwab to explain what eccentric and concentric training are—or get to MLHF and try for yourself.
