High knees with a jump rope combines two powerful exercises into one intense cardio movement. By driving your knees up toward your chest while turning the rope, you dramatically increase the cardiovascular demand and core engagement. It's a go-to technique for HIIT intervals and fat burning.
How to do high knees
- 1
Start with the alternate foot step at a comfortable pace.
- 2
Gradually begin to drive your knees higher — aim for waist height.
- 3
Each knee should come up as the rope passes under your feet.
- 4
Pump your arms naturally — the rope handles will still turn with your wrists.
- 5
Maintain an upright posture — don't lean back to lift your knees.
- 6
Start with 15–20 second intervals and build up to longer sets.
Common mistakes
Leaning backward
Stay tall with your core engaged. Leaning back is a sign your hip flexors need more strength.
Losing rope rhythm
Start with moderate knee height. You can go higher as your coordination improves.
Going too hard too soon
High knees are exhausting. Use them for short HIIT bursts, not entire workout sessions.
Pro tips
- ✓High knees are perfect for HIIT: 20 seconds of high knees followed by 40 seconds of easy basic bounce.
- ✓Focus on bringing your knees up, not your feet back — it's a hip flexor exercise, not a heel-to-glute movement.
- ✓Pair with a jump rope counter app to track your peak jumps-per-minute during high knee intervals.
