How It Works

Standing reach + vertical leap. Must exceed 131.4" to dunk.
Expert Tips
Plyometrics
Box jumps, depth jumps 3x/week — add 2–4" in 6 weeks.
Strength
Squats, deadlifts — aim for 1.5–2× bodyweight before heavy plyos.
Approach
One-foot takeoff with run adds 4–6" vs standing two-foot.
Flexibility
Hip flexor and ankle mobility improve force production.
