The Bear Complex combines a power clean, front squat, push press, back squat, and another push press into one continuous sequence. Each rep challenges your strength, coordination, and endurance as the bar gets heavier and fatigue sets in.

The goal? Move well, stay consistent, and challenge yourself. 💪
