The split jump is a bodyweight plyometric drill performed from a lunge stance, jumping high enough to swap the front and rear foot in the air before landing back in a lunge. It is the same leg action the library also files as thescissor jumpand the alternating split squat jump; the split jump name emphasises the depth, so each landing sinks to lunge depth and each jump starts from there rather than from a shallow hop. That makes it a power drill, not a conditioning one. Use it early in a lower body session.
What Muscles Does the Split Jump Work?
- Primary: Quadriceps, gluteus maximus
- Secondary: Hamstrings, gastrocnemius and soleus (calves), hip flexors of the rear leg
- Tertiary: Gluteus medius (side glute), rectus abdominis, erector spinae
How Do You Set Up for the Split Jump?
Clear a strip of non-slip floor a little longer than your stride and keep the ceiling in mind before you jump. Step one foot forward and the other back into a stance about two and a half foot lengths long. Bend both knees until the front thigh is close to parallel and the rear knee sits a hand's width off the floor. Stack the torso over the hips, ribs down, hands loose at your sides.
How Do You Perform the Split Jump?
- Settle into the bottom of the lunge with the front foot flat and the rear heel raised.
- Push both feet through the floor and jump straight up as high as you can.
- Swap the legs at the peak so the front foot travels back and the rear foot travels forward.
- Reach full extension with the hips open and both knees straight at the top of the jump.
- Land on both feet together in the mirrored stance and sink back to lunge depth under control.
- Pause a beat at the bottom, then jump again from that depth for the next rep.
What Are the Key Form Cues?
- Jump for height, not for speed: give each rep a full effort and reset between them, since depth and height are what this version trains.
- Front shin vertical on landing: land with the knee over the ankle so the quad absorbs the drop instead of the joint.
- Split the feet evenly so both legs share the take-off rather than the front leg doing it alone.
- Keep the hips square to the front while the legs pass each other in the air.
- Let the rear knee bend deeply on landing without letting it strike the floor.
What Are the Most Common Mistakes?
- Adding dumbbells before the landings are quiet: the load lands with you and the depth collapses, so keep it bodyweight until every rep is silent.
- Turning the set into fast shallow hops: the jump height drops and the drill becomes conditioning, so rest between reps and stay deep.
- Letting the front knee cave inward: knee valgus under a jump landing loads the medial knee ligaments, so land with the knee over the second toe.
- Landing heel first on the front foot: the calf skips its share of the shock and the impact runs into the knee and hip, so meet the floor with the whole foot.
- Banging the rear knee down: an overlong stride leaves no room to absorb the landing, so shorten the stance.
What Are the Best Split Jump Variations?
- Alternating lunge: step through instead of jumping, a no-impact regression for learning the depth.
- Split jack: the arms swing overhead with each switch, adding rhythm and upper body work.
- Single-side split jump: keep one leg forward for the whole set, loading one quad and one rear hip.
- Rear-foot-elevated split jump: the back foot starts on a box, deepening the front leg range.
- Dumbbell split jump: light dumbbells at the sides add load once the landings are clean.
How Do You Progress the Split Jump?
- Stay bodyweight until 8 quiet reps per leg, then hold 10 pound dumbbells at the sides.
- Build from 5 jumps per leg to 8 before adding load.
- Add a set at a time up to four, or a second plyometric day in the week.
- Jump from a deeper lunge, or pause two counts at the bottom before each jump.
How Should You Program the Split Jump?
Put the split jump early in a lower body session, after the warm-up and before squats or lunges, once or twice a week. Work 3 to 4 sets of 5 to 8 jumps per leg with 60 to 90 seconds of rest so each rep is fresh. End the set as soon as the jumps lose height. Pair it with a heavy split squat, which trains the same stance under load.
