For glute growth
For glute growth, the two are close. Barbell back squat rates slightly higher: easier to progress, more stretch.
Step-up is easier on the joints.
Both are good choices, and they train the glutes differently. Using both across your week covers more of the muscle than either alone: in studies, varied exercises grew parts of a muscle that one exercise missed. (Fonseca et al., 2014; Costa et al., 2021)
The research score comes from these, scored by hand from the studies. Lifter scores appear once an exercise has 10 ratings. How scores work
Barbell Back Squat. Deep squats grew the glutes about three times more than half squats in one study.
Step-Up. A high box puts the front glute under load from a deep hip bend. Light on the joints, capped by balance.
For cycling, the two are close. Step-up rates slightly higher: easier to learn and fit in. Barbell back squat carries over more directly to cycling.
For quad growth, barbell back squat rates well ahead on our research criteria: easier to progress, more of the work on the quads. Step-up is easier on the joints.
For running, step-up rates higher on our research criteria: easier to learn and fit in. Barbell back squat does more to prevent injuries.
For skiing & snowboarding, barbell back squat rates higher on our research criteria: more carry-over to skiing & snowboarding, more injury protection. Step-up is easier to learn and fit in.
For hybrid & fitness racing, the two are close. Step-up rates slightly higher: easier to learn and fit in. Barbell back squat carries over more directly to hybrid & fitness racing.
For glute growth, the two are close. Barbell back squat rates slightly higher: easier to progress, more stretch. Step-up is easier on the joints. Both are good choices, and they train the glutes differently. Using both across your week covers more of the muscle than either alone: in studies, varied exercises grew parts of a muscle that one exercise missed.
Step-up is easier: it’s easy to learn, while barbell back squat takes some practice.
Barbell back squat needs a barbell and a squat rack, so for most people it’s a gym exercise. Step-up needs dumbbells and a plyo box, so for most people it’s a gym exercise.
Step-up: it rates Excellent for joint and recovery cost in our research rubric, against Fair for barbell back squat.
