Dumbbell Step Ups target the quads, glutes, and hamstrings while engaging the core for stability. Hold a dumbbell in each hand at your sides, and step onto a sturdy platform or bench with one foot. Drive through the heel to lift your body up, bringing the trailing leg to meet the leading leg, then step back down with control. This exercise improves lower-body strength, balance, and functional movement. Gymcheq emphasizes controlled motion and proper posture for safe and effective training.
