The Tactical Mobile System adds another VECTOR and delivers up to a total of approximately 200 pounds of resistance. With 2 VECTORs anchored side-by-side you no longer need to purchase much larger, more expensive pieces of functional training equipment. You can also set-up one VECTOR at lighter resistance levels and the second one at higher resistance levels to speed exercise transition times. Our Long Torso Strap offers even more multi-directional exercise options and, as with the Base Mobile System, you can grow into our Pro Mobile System at anytime in the future.
