Put simply, a lifter who has better GPP has more potential to get in productive training sessions more frequently over the course of a year.
After 3-4 years of this training, this can mean a massive difference in gains between a lifter who has developed their GPP and a lifter who hasn’t.
How Much Cardio Should You Do?
For most lifters, 3-4 cardio sessions per week at 30 minutes a pop in the aerobic zone are all you need to elicit beneficial physiological adaptations. When properly structured with your lifting split, these sessions shouldn’t impact you short-term performance, either. Give cardio a chance before dismissing it—it could translate into gains on gains on gains.
