Elbow to Knee Twists
The Elbow to Knee Twists is a compound movement that trains the quadriceps with help from core and front delts. This guide covers the setup, the execution, the mistakes worth fixing early, and how to program it.
This is conditioning work: continuous effort that raises your heart rate, builds work capacity and burns meaningful calories, with the quadriceps driving the movement. It complements lifting rather than replacing it.
Who it is for. Anyone building fitness or supporting a fat-loss phase. Put it after lifting, or on a separate day, so it does not blunt your strength work.
Muscles worked
The prime mover here is the quadriceps, with core and front delts assisting — which is why this movement earns its place as more than a single-muscle exercise.

How to do it
- Clear the space you need and set up your bodyweight before you start the clock.
- Warm up for a few minutes so the first interval is not the warm-up.
- Decide on the work and rest periods before you begin, rather than going until you are wrecked.
- Move at a pace you can repeat — the aim is a sustainable effort, not one heroic round.
- Keep your technique sharp as you tire; sloppy reps under fatigue are where injuries come from.
- Finish the last interval feeling like you could have done one more.
Breathing. Breathe rhythmically and through the nose where you can. Match your breath to the movement rather than holding it.
Form cues that matter
- Pick a pace you can hold for every round.
- Breathe rhythmically rather than gasping.
- Stop the set when technique degrades.
- Going flat out on the first round and fading
- Letting form fall apart as fatigue builds
Common mistakes
| The mistake | Do this instead |
|---|---|
| Going flat out on the first round and fading | Start a notch below what feels possible and hold it. |
| Letting form fall apart as fatigue builds | Cut the interval short; conditioning is not a reason to move badly. |
| Doing so much it eats into your lifting recovery | Keep hard conditioning to two or three sessions a week alongside a lifting program. |
What makes this variation different
The Elbow to Knee Twists is a specific version of this movement, and the details in its name change how it should be performed.
- Using only your bodyweight means you can train anywhere, and it keeps the whole body involved in stabilising the movement. Progress comes from leverage, range and reps rather than from adding plates.
Sets, reps and rest
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Strength | 3-5 | 20-40 s hard | 30-90 s |
| Muscle growth | 3-4 | 30-60 s | 30-90 s |
| Endurance | 2-3 | 2-20 min | 30-90 s |
How to progress
Add time or difficulty rather than load. Once you can hold the position cleanly for the top of the range, progress to a harder variation or add external resistance instead of simply holding longer.
Variations and alternatives
If you do not have the equipment, or you simply want to rotate the stimulus, these 8 movements train the quadriceps in a similar way.
- Alternate Punching — Bodyweight
- Arm Raise Step in Place — Bodyweight
- Barbell Power Jerk — Barbell
- Bodyweight Skipping — Bodyweight
- Briskly Walking — Bodyweight
- Burpee — Bodyweight
- Butt Kicks — Bodyweight
- Celebratory Knee Drives — Bodyweight
Key takeaways
- Pick a pace you can hold for every round.
- Breathe rhythmically rather than gasping.
- Work in the 30-60 s rep range for muscle growth, leaving a rep or two in reserve on most sets.
- Full range of motion on the Elbow to Knee Twists matters more than the weight on it.
- Progress gradually and keep technique identical as the load goes up.

FAQ
What muscles does the Elbow to Knee Twists work?
It works the quadriceps as the prime mover, with core and front delts assisting.
How many sets and reps should I do on the Elbow to Knee Twists?
Two to four sets is plenty. Work in the 30-60 s range and focus on the quality of each rep rather than the number of them.
What can I do instead of the Elbow to Knee Twists?
