"Stand facing a sturdy box or bench that’s about knee height. Hold a pair of dumbbells at your sides or a barbell across your upper back. Place your entire foot on the step so your heel is planted and toes are forward. Keep your chest tall, shoulders back, and core braced."
Key point: “Your working leg on the step should do most of the lifting—avoid pushing off too much with the back leg.”
"Drive through the heel of your front foot to step up onto the platform, bringing your back foot up until you are standing tall. You can either step back down with the same leg or alternate legs each rep. Move slowly and with control, especially on the way down."
"Exhale as you drive up, inhale as you step back down."
