What these mean

Target tension.: Whether the muscle you’re training is what gives out first, not your grip, balance or other muscles.
Loaded stretch.: How hard the muscle works while stretched. Training it there is linked to more growth.
Progression.: How easily you can keep adding weight in small steps over months and years.
Low cost.: How easy it is on your joints and recovery, and how quickly you can learn it.
