DTW founder Dr. Tom Stewart has been involved with strength training programs for over 30 years as a Physical Therapist. Dr. Stewart worked with DTW engineer Paul Lando to develop the PDM as an effective dynamic training device utilizing closed kinetic chain exercise principles. The PDM provides consistent resistance when pushing or pulling while avoiding the risk of injury when using sleds and ot
her traditional training devices. The PDM easily adjusts to accommodate any size and range of athlete for any sport – football, baseball, basketball, hockey, track, wrestling, gymnastics, soccer, and rugby. Any athlete wanting to develop lower trunk and lower extremity strength will be challenged by a PDM workout.
