Outer Leg Reap Drill: A Complete Guide
Quick Intro
Outer Leg Reap Drill is a Martial Arts Drills exercise performed by off-balancing a partner toward their rear corner, then sweeping the same-side leg backward through their supporting leg with the sole of the foot while pulling with the arms. Timing the leg reap to the moment the partner’s weight sits on that leg is what makes this throw work.
Equipment Needed
A padded surface is strongly advised for the repeated falls, and the drill needs a partner able to take the throw and the fall safely.
Why It Matters
Reading the moment the partner’s weight settles, pulling with the arms and sweeping the leg all have to come together in one motion. The largest glute muscle (gluteus maximus) and a muscle at the back of the thigh (hamstrings, biceps femoris) drive the sweeping leg, and a muscle at the front of the hip (hip flexors, iliopsoas) supports the stepping motion. The muscles along the sides of the abdomen (obliques) generate the rotation behind the sweep, and the lower back muscles (erector spinae) brace the spine through the throw. The inner thigh muscles (adductors) help control the base leg, a large back muscle (latissimus dorsi) drives the pulling arm and the biceps (biceps brachii) assist the grip through the pull.
When to Do It
Outer Leg Reap Drill works well within a grappling-focused session, added once basic grip-fighting and off-balancing already feel familiar. Two to three sessions a week is a reasonable pace, always with a partner comfortable taking the fall.
Anyone with a current hip, knee or low-back issue should get individual guidance before adding this drill, since the sweeping leg and the pulling motion both load those areas directly.
Getting Ready
Off-balancing the partner to their rear corner without attempting the leg sweep yet checks the grip and the timing this throw depends on. A few slow, cooperative reaps preview the full throw before a complete rep at speed is attempted.
Step-by-Step Instructions
- Secure the grips. Establish sleeve and collar control, or the equivalent hold.
- Off-balance the partner. Break their posture toward their rear corner.
- Time the reap. Sweep the same-side leg backward through their weighted leg.
- Pull through. Drive the pull with the arms as the leg sweeps.
How Many, How Often
Outer Leg Reap Drill is dosed by reps, with each full off-balance-and-reap sequence counting as one.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to timing the reap to the partner’s weighted leg | 3 sets of 3 to 4 reps per side |
| Intermediate | The off-balance and the reap connect smoothly | 3 to 4 sets of 4 to 6 reps per side |
| Advanced | Comfortable throwing against light resistance | 4 sets of 6 to 8 reps per side |
Timing the reap to the moment the partner’s weight sits on that leg matters more here than how hard the sweep lands, since a reap thrown at an unweighted leg does nothing however much force goes into it.
Modifications and Variations
As an easier version, Entry and Grip Only practices the grip-fighting entry and the off-balance to the rear corner in isolation, without executing the reaping sweep.
As a harder version, Outer Leg Reap to Finish carries this entry and off-balance through to the full sweeping reap and a controlled landing.
Common Mistakes to Avoid
Reaping before the partner’s weight settles. Sweeping the leg while it’s still unweighted wastes the attempt, however well the grip and the off-balance went beforehand. The reap lands at the instant the weight shifts onto that leg.
Pushing the leg. A straight push at the leg rarely clears it, while a sweeping motion with the sole of the foot sends it out cleanly. The foot travels through the leg.
Letting the pull and the reap happen out of sync. Timing the arm pull separately from the leg sweep splits what should be one combined motion into two weaker ones. The pull and the reap land together.
After Your Set
A few slow hip circles release the hips after repeated throws. Folding forward from the hips with soft knees for a few breaths eases the hamstrings and the low back that drove each sweeping motion.
Going Deeper
Off-balancing a partner and then catching their weighted leg at the right instant asks for a reading of their weight that a static drill never demands. The reap tends to land a half-beat early, before the weight has settled onto that leg. Slowing the off-balance down and waiting for the weight shift to commit fixes this faster than repeating a fast reap that keeps missing the timing.
Someone new to this drill generally manages a slow, cooperative reap within the first few sessions, then works toward a well-timed throw against light resistance over the following couple of weeks.
How to Know You’re Improving
- A reap that lands at the moment the partner’s weight settles on that leg
- A sweep that travels through the leg with the sole of the foot, not a push
- A pull and a reap that land together as one combined motion
- A throw that holds up once the partner starts resisting
Catching the weighted leg matters more than how hard the sweep lands.
Muscles Worked
- Gluteus Maximus (the largest glute muscle, extending the reaping hip to sweep the leg through)
- Biceps Femoris (a muscle at the back of the thigh, whipping the sole of the foot backward)
- Iliopsoas (the hip flexor group at the front of the hip, bringing the reaping leg forward before it swings back)
- Obliques (the muscles along the sides of the waist, turning the trunk to direct them to the rear corner)
- Erector Spinae (the muscles running along the length of the spine, holding posture as their weight shifts)
- Adductors (the inner thigh muscles, holding the standing leg planted through the reap)
- Latissimus Dorsi (a large back muscle, pulling the collar down to break their balance)
- Biceps Brachii (the front of the upper arm, bending the elbow to keep the sleeve grip tight)
FAQ
Why does the timing of the reap matter so much? An unweighted leg moves out of the way when swept, while a leg carrying the partner’s weight has nowhere to go once the sole of the foot sweeps through it, which is the mechanism behind this throw.
Is this harder than isolating the entry and off-balance alone? Yes, adding the timed leg sweep on top of the grip-fighting and the off-balance asks for more coordination than practicing the entry alone.
Is some hip or low-back fatigue after this drill normal? Yes, a worked feeling through the hips and the low back after a full set of throws is expected. Hip or knee pain that doesn’t ease off between sessions is worth a visit to a doctor or physical therapist.
Does the entry come before the reap? Yes, Entry and Grip Only builds the grip-fighting and off-balance, which are worth having solid before the timed sweep is added.
How often should the outer leg reap be drilled? Two to three times a week, with a partner comfortable taking the fall, suits most people building toward this skill.
