Calculating Your Vector Resistance

When using the TRX Suspension Trainer, there are three principles you can apply to modify exercise intensity: Pendulum Principle, Stability Principle and Vector Resistance Principle. Vector Resistance Principle applies to exercises that happen from a standing position. When standing straight up with your base of support directly beneath your center of gravity, your legs support 100% of your bodyweight. As your body angle steepens (as in the TRX Chest Press), your center of gravity moves outside your base of support and weight transitions onto the TRX, which adds resistance to the exercise. The steeper your body angle, the greater the resistance or intensity of the exercise.

 

Use the chart below to calculate the Vector Resistance (i.e., how much of your bodyweight you are moving based on the angle of your body) for all TRX exercises that happen from a standing position.
