Jumping jacks

Execution

Stand with feet together, arms at your sides. In a single jump, spread your feet to about one and a half times shoulder-width while raising your arms laterally overhead (hands meet or nearly meet at the top). Return to the starting position with a second jump: feet together, arms at your sides. The movement is fluid and continuous; arms and legs synchronize perfectly. Land on the balls of your feet with your knees slightly bent to absorb each jump.

Breathing

Inhale as you spread your arms and legs; exhale as you return to the starting position. Your breathing rhythm adapts naturally to the movement cadence — keep it fluid and steady.

Benefits

• •Full-body warm-up in seconds: simultaneously activates cardio, shoulders and legs
• •Improves arm-leg motor coordination and sense of rhythm
• •Zero equipment, zero complex technique: accessible from the very first session
• •Engages the adductors and deltoids, often undertrained in classic routines
• •Quickly raises heart rate to prepare the body for more intense effort

Variants

Our tips

• 1.Keep your knees slightly bent on landing to protect your joints
• 2.Arms rise straight out to the sides, not in front of you — the movement comes from the shoulders
• 3.Stay on the balls of your feet, never land heel-first
• 4.Find a steady, sustainable rhythm rather than going maximum speed from the start

Common mistakes

• •Landing on your heels — creates excessive impact on knees and ankles. Stay on the balls of your feet.
• •Arms passing in front of the body instead of rising laterally — reduces deltoid work and breaks the rhythm
• •Stiff knees on landing — always bend your knees slightly to absorb the impact
• •Too small a range of motion (hands don't reach overhead) — perform the full movement for effective work
• •Irregular or jerky rhythm — maintain a constant, fluid cadence to maximize the cardiovascular effect
