Low-Impact Jumping Jacks
Low-impact jumping jacks give you the heart-pumping, full-body rhythm of a classic jumping jack without both feet leaving the ground at the same time. One foot always stays in contact with the floor, which dramatically reduces the jarring force on your knees, hips, and ankles. This makes it a great way to warm up your whole body, get your blood moving, and practice coordination — all without pounding your joints.

Form cues
- 01
Stand tall with your feet together and arms resting at your sides.
- 02
Step your right foot out to the side while raising both arms out and up toward the ceiling — stop when your arms are roughly at shoulder height or as high as is comfortable.
- 03
Bring your right foot back in and lower your arms at the same time.
- 04
Immediately step your left foot out to the side and raise your arms again, mirroring the first movement.
- 05
Keep a soft bend in your knees throughout — never lock them straight.
- 06
Move at a steady, comfortable pace so your arms and legs finish each rep together.
- 07
Keep your chest lifted and your gaze forward, not down at your feet.
- 08
Breathe in as your arms go up, breathe out as they come back down.

Common mistakes
Locking the knees on the step-out — if your legs feel stiff or you hear your heel slam the floor, soften the knee before your foot lands.
Arms barely moving — if your hands stay below chest height the whole time, you're missing the upper-body work; aim to reach at least shoulder height.
Stepping too wide — if your hips shift heavily side to side or you feel strain in your groin, shorten the step so your feet land only slightly wider than your hips.
Rushing the pace until the arms and legs fall out of sync — slow down until both reach their end position at the same moment.
Holding your breath — if you feel your face getting tight or you need a big gasp between reps, you're not breathing; match your breath to the movement.
Scale it
Easier and harder variations
Easier
Stand beside a wall or chair and lightly rest one hand on it for balance while you step side to side with smaller arm raises.
Use this if you feel unsteady, are just starting out, or are working around a balance issue.
Harder
Add a small resistance band just above your ankles to increase the effort of each step-out, or raise your arms all the way overhead on every rep.
Try this once the standard version feels easy and you want more challenge without adding impact.
Note
Do seated jacks: sit in a sturdy chair, tap one foot out to the side while raising both arms, then alternate sides — all movement happens from the seat.
Use this if you have significant knee, hip, or balance concerns that make standing side steps uncomfortable.
