The Importance of Single Leg Training

by William Sturgeon on August 15, 2018

William Sturgeon, RKC-II Split Squat

We spend a lot of time training our clients with bilateral movements, such as squatting and hinging. These dynamic and explosive movements are done in a stationary position. When we choose exercises for our clients—or for our own training—the exercises should always be purposeful movements applicable to their lifestyle and goals. Whether you coach athletes or the general population, everyone moves unilaterally.

Whenever moving in any plane of motion, we move by stepping with one foot first. We move unilaterally throughout our whole day. Unless we’re stationary for a while, we do not spend much time in a bilateral stance. Knowing that all movement is initiated with one foot, why do we place such an emphasis on bilateral movements when training our clients?

There are many reasons to include unilateral exercises in our training programs. But, one of the main reasons I include single leg training is to allow me to train my clients’ weaknesses. While it is easy to temporarily correct a client out of a knee valgus during a squat with the cue “spread the knees apart,” it doesn’t really fix the problem. By including single leg exercises you can help strengthen your client’s asymmetrical weaknesses—which will also strengthen their bilateral movements.

Another reason I favor unilateral movements, is because they can help rehab and prevent injuries. If you train athletes or the general population, your job is to help them reach their goals—and keep them safe during their training. Another great benefit unilateral exercises offer over bilateral exercises is that they promote even more ankle stability and strength. Strengthening the ankles can reduce the chance of ankle injuries—which often lead to knee and hip pain.

The following are a few of my favorite single leg exercises:

Split Squat (see photo at beginning of post)

  • Start at the bottom of a split squat position.
  • Hold a kettlebell as if you were about to do a goblet squat (place the kettlebell near the collar bone).
  • Push evenly with the foot—through the ball of the foot and the heel to stand.
  • Lock the knee at the top of the movement while squeezing the glutes.
  • Lower yourself down slowly, and do not let the knee bang against the ground.

Lateral Lunge

  • Start by holding the kettlebell in the rack position, or at the chest (the goblet squat position).
  • Take a large step to the side.
  • Bend your knees and push your hips back.
  • Return to the starting position by pushing through the inside of the foot you used to step to the side.

Curtsy Lunge

  • Start by holding the kettlebell at the chest (the goblet squat position).
  • Step back and behind your other leg.
  • Slowly lower your hips until the knee lightly touches the ground.
  • Push through the front leg, and return to the starting position.

Weighted Single Leg Glute Bridge

  • Begin on your back, and hold a kettlebell at your belt line.
  • Raise one leg off the ground by lifting the knee.
  • Tuck your chin and rib cage down as you press the heel of the other foot into the ground
  • Raise the hips up and squeeze the glutes.
  • Lower yourself down slowly and return to the starting position.

Single Leg Rear Deadlift (RDL)

  • Place both hands on the kettlebell handle.
  • Keep a slight bend in the knee and push your hips back.
  • Keep a straight spine and lower the kettlebell below the knee by bending with the hips.
  • Return to the starting position by pulling your chest and hips up as you stand tall.

Single Leg Deadlift

  • Begin with the kettlebell on the ground in line with your toes.
  • Bend at one knee and begin to hinge down while pushing your hips towards the wall.
  • Keep your chest up while lowering yourself through the hips.
  • Return to the starting position by standing tall.

Single leg exercises are essential moves to consider in your kettlebell training.

Beyond the See-Saw Press: Two New Variations

by Nick Collias on August 8, 2018

Z-Saw Kettlebell Press Nick Collias
Some lifts just never feel quite right, no matter how hard we try to force them to do so. Others are a willing dance partner from the first rep. And from the first time I tried it, the see-saw press just felt right.

Unlike the single-arm press, which took months (er, years) to share the ideal groove, the see-saw offered it up instantly. And because it’s a rhythmic push with a bit of a pull (or an eccentric push that feels like a pull), it demands that all manner of anterior, posterior, lateral, and deep core muscles get in the game of tug-o-war. Any experienced RKC can tell you that this extra activation usually allows you to get 2-3 extra reps, maybe more, with any given weight than what you’d manage with either single-arm or double-arm presses.

That translates to extra strength, extra volume, extra activation, and extra-efficient training. Extra awesome.

Those are all reasons to try the see-saw press. But they’re also reasons to explore different variations of the movement. Here are two variations that have quickly become my two favorite presses, period.

To be clear, I make no claim to inventing either of them. Somebody else probably did long ago. I just happened across them in my training, picked them up, and am now passing them along.

Z-Saw Press

This is nothing more than a seated see-saw press in a straddle position, or what is known as a Z-press. But that alteration changes the lift dramatically.

What I dig about it:

  • Sure, it brings the wicked shoulder pump, but it also ties in more total upper body musculature than any press I’ve tried—even more than the standing see-saw press. All the postural muscles of the upper back light up, but so does the core. When those groups are both working hard, I know I’m doing something right.
  • Lumbar hyperextension is pretty much impossible with this lift. Not so with the standing see-saw. This makes it a great way to work around an achy lower back, or just one, like mine, that just doesn’t like to work hard early in the morning when I tend to train.
  • No clean is needed. That’s not an advantage or disadvantage; it’s just a feature of the lift. This means it lends itself more cleanly to an upper/lower split, if you prefer that approach.
  • Perhaps because the upper back and core are so integrated, I find it also lends itself better than other press variations to grinding out a few hard reps at the end of a set, while still being safe on the shoulder joint.

This is one reason why I like it with a DeLorme Protocol-style approach:

10 reps light, or around half of 10RM
10 reps medium, or about .75 of 10RM
10 reps with more or less a 10RM

Look forward or look up; either way, your postural muscles and pressing muscles will both work overtime.

Keeping a set at a 10RM or lighter also keeps you from having to figure out how to get two seriously heavy bells into position. Just curl it up and go.

One more technique note: In a recent email, Master RKC Andrea Du Cane mentioned that she recommends most people—men in particular—sit on a yoga block or something similar during Z-press variations, because otherwise they often struggle achieve a neutral pelvis and spine position on the ground. Me, I like something about half to two-thirds yoga block-height, like one of those hardcover college textbooks you haven’t done anything with in a long time. The Modern Library edition of Plutarch’s Lives of the Noble Greeks and Romans is just about perfect.

Swollias Press

This movement took on my nickname at work (I do work at, after all), simply because I’d never seen it before, and the nomenclature alternatives are all pretty complicated. “Alternating see-saw kettlebell thruster,” anyone? No thanks. Let’s go with Swollias.

As with the Z-saw, this isn’t a new lift so much as it is a combination of existing ones. Here’s how to do it:

  1. Clean a pair of kettlebells, either from a dead stop or with a swing. You can do it with two matching weights, or two uneven ones. It works great with both.
  2. Perform a single front squat, and on the way up, press one of the kettlebells up while keeping the other in the rack.
  3. Lower the top bell into the rack. A second clean is optional here.
  4. Squat again, and on the way up, press the other bell. You can then set the kettlebells down and shake it off before going again, or you could keep piston-pumping reps as long as you want.

What’s the advantage? Well, having a bell in the rack means you’re forced to keep an upright torso and tight core. I like the single-kettlebell thruster, but find it can get a little sloppy and forward-leaning under fatigue. This variation holds a little firmer, in my experience.

"Swollias" Kettlebell Combo Sequence Nick Collias

Lots of cleans, lots of squats, lots of time in the rack. What more do you want?

On the flipside, it doesn’t require the same level of thoracic mobility as a double-kettlebell press or thruster, and once again, lumbar hyperextension is hard to slip into with this variation. Definitely not so with the double kettlebells.

With heaver weight, I like to treat these as a little mini-complex, kind of like Dan John’s “Armor-building” complex of two cleans, one press, and three squats. One round of clean, squat, press, clean (optional), squat, press every 30 seconds, or on the minute, is a great routine. Do it for 10-20 minutes, and it adds up to lots of cleans, lots of squats, lots of time in the rack.

Alternately, you could use a lighter weight, up the reps, and just see what cries “Uncle” first.

How To Use These Lifts

There’s a time to train like you’re chasing something—say, a half-bodyweight press for an RKC-II certification—and there’s a time to train like you’re not. And when I’m not chasing, I like to mix my presses up. A lot.

For the last few months, my favorite way to do this is to use Dan John’s press and suspension strap circuit from this article on as a template, and swap out press variations based on whatever feels good that day. Both of these press variations have been regulars in the batting order.

Don’t confuse this with “program hopping,” that oft-maligned symptom of exercise ADD. The parameters and the basic movement patterns don’t change much; just the specifics do. If I want to change every workout, fine. If I want to do the same thing for three weeks, fine.

This approach keeps me excited to train, allows me to sneak into moderate rep PRs regularly, but also allows—or maybe forces—me to learn and explore new lifts, either those that I see out in the world, or that I cook up on my own in a moment of living room inspiration. These are two of the latter. Enjoy!
