I love to see research that continues to confirm what we are doing. Here is some research that a TriSystem Client, Dr. Barb Levy just emailed us.
Conclusions
These findings suggest that single-set routines can be a time-efficient strategy for promoting muscular adaptations in resistance-trained individuals, even when transitioning from higher-volume programs. Training to failure in single-set routines may modestly enhance some measures of muscle hypertrophy and power, but not strength or local muscle endurance.
