For Coaches: Coaching Double-Unders to a Full Class
Updated: 24 hours ago
You hear a double-under class before you see it. A few ropes hum in a steady rhythm. Others slap the floor, stop, start again. Somewhere in the corner there's a sharp crack and a quiet "ow" as a rope finds a shin. And over all of it, the coach's voice trying to cue fifteen different problems at once.
I've been every person in that room. I was the athlete in the corner collecting rope marks on my shins, sure my timing was just broken. I jumped higher and higher, thinking that bought me time, and it only made me tired faster. And later, as a coach, I was the voice trying to fix everyone at once. Neither version of me was very effective.
That noise is normal. Tripping is part of learning this skill, and a room full of missed reps isn't a sign that the session is failing. What turns it into productive practice is structure: the right rope for each athlete, enough space, and a way to split the class so each person works on the one thing that'll move them forward. Here's how I set up a double-under session for a full class right now, using stations and three clear tiers. I'm still a newer coach and still adjusting this setup, so take what fits your gym and leave the rest.

Before the Ropes Move: Sizing and Spacing
Start with the ropes. A common guideline for sizing is to stand on the middle of the rope with one foot and pull the handles up; the cables should reach somewhere around the lower chest to the armpits. Beginners generally do better with a slightly longer rope and a little more weight in the cable, which makes the rhythm easier to feel. More experienced athletes often prefer a shorter, lighter speed rope. If your gym has shared ropes, sort them by length and label them so athletes can find the right one quickly.
Then set the space. Each athlete needs clear room in every direction, roughly the length of their rope plus some, so nobody can clip a neighbor. Arrange athletes in staggered rows or lines facing the same direction, with you able to see everyone. A firm, flat surface helps; very soft mats swallow the rope and make timing harder.
Three Tiers, Three Jobs
Rather than teaching the whole class the same drill, sort athletes into tiers based on what they can already do. A quick self-test sorts most people in under a minute: 30 seconds of single-unders, then three attempts at a double-under.
Tier one: building rhythm
These athletes can't yet string 30 to 50 relaxed single-unders, or their singles are high, loud and tense. Their job is rhythm. Drills include steady singles with a small, quiet bounce on the balls of the feet, and pogo hops without a rope at a slightly higher jump. Coach relaxed shoulders and hands close to the hips. Double-unders aren't the goal today; smooth singles are.
Tier two: first doubles and single-single-double
These athletes have good singles and are working toward their first doubles or short strings. The most useful drill is a pattern of two or three singles followed by one double attempt, then back to singles. The cue I use most is "same jump, faster wrists": the jump gets a little higher, but the speed comes from the wrists, not from bigger arm circles. That cue is the one that finally clicked for me, and I've watched it click for several of my athletes since. Once they land doubles, move to alternating single and double, then to two doubles in a row.
Tier three: strings and fatigue
These athletes can do double-unders but lose them in workouts. Their work is sets of a fixed number, such as 20 to 30 double-unders, with short rest, or short intervals pairing double-unders with a movement that raises the heart rate. The focus is breathing, a relaxed upper body and restarting quickly after a miss instead of stopping to reset.
Coach's cue: Tripping is part of teaching, so coach the restart, not the miss.
Running the Stations as a Class
With a full class, I set three zones of the floor, one for each tier, and work in blocks: about two minutes of practice followed by about a minute of rest, repeated for 10 to 15 minutes. The rest block is when I coach. During practice, I walk the room and pick one athlete per tier to cue. During rest, I gather a tier for a brief demonstration or share a single cue with the whole group.
Keep cues short and specific:
"Quiet feet" for athletes landing heavily or jumping too high
"Hands by your pockets" for arms swinging wide
"Tall and relaxed" for piking or kicking the legs back
"Same jump, faster wrists" for athletes trying to jump higher to create time
"Restart now" for anyone who stops to reset after every miss
Encourage athletes to move up a tier within the session when they're ready, and back down if fatigue makes technique fall apart. Tiers are working groups, not labels.
Protecting Calves, Achilles and Shins
Rope work is repetitive impact on the lower legs. High volumes of jumping, especially for athletes new to it, can leave calves and Achilles tendons sore for days. I remember walking down stairs very carefully the morning after one overenthusiastic practice session. Keep total practice time reasonable, stay on a forgiving surface where possible and build volume across weeks rather than in one session.
Tell athletes plainly: mild calf fatigue is expected, but sharp pain in the Achilles or shin, or pain that persists, is a reason to stop. If pain continues, they should see a physiotherapist or doctor. And rope strikes, while painful, are common; long socks or leggings help the nervous beginners.
Scaling Double-Unders in the Workout
Practice time should connect to the workout that follows. Tier one athletes typically do single-unders at a ratio chosen so the time on the rope stays close to the intended stimulus, rather than being limited by attempts. Tier two athletes can take a fixed attempt window, such as 30 to 45 seconds of double-under practice per round, then move on. Tier three athletes do the prescribed reps, perhaps with a planned break strategy.
Keep the stimulus in mind. If double-unders are meant to be a short, fast piece, athletes shouldn't spend three minutes tripping in every round.
Growing the Skill Beyond One Session
One class won't solve everyone's double-unders. A consistent approach across several weeks will. Revisit the tiers regularly, celebrate first doubles loudly and keep coaching the restart. When a tier-two athlete lands their first one and the whole room cheers, you'll remember why this noisy session is worth running. Respect the details, keep showing up, and the room will get quieter as the ropes get faster. Coaches with more years on the floor probably have drills I haven't tried yet, and I'd love to learn them.
For athletes who want structured rope and conditioning work between classes, ATHLETESPHERE programming complements what you do in the gym.
