If you work with basketball athletes or taller athletes, you may have noticed that these athletes may struggle with not only double leg squatting but also single leg squatting. This is because their femurs tend to be longer than the average folk.
This comes back to simple physics as a longer lever is more difficult to control. And if an athlete has trouble controlling movements, injuries are sure to occur. Every joint within our body needs a certain amount of mobility (movement) and stability (control). If mobility is established then we need to add stability/control to it. In our case of long femurs and squatting, the first step is to make sure there is adequate mobility within the hip joint. If that is good we need to move onward to see why an athlete still has trouble performing the movement. The movements that tend to be the hardest to control are the eccentric actions of the squatting movement which are internal rotation and adduction. Now what muscles help control these femoral movements?
Namely the muscles that help to externally rotate and abduct the hip which are the gluteal muscles.
The Glute max, medius and minimus play a huge role in developing femoral control. And we have to train these muscles in ways that help to work on these actions.
If we don’t include exercises that help to work on femoral control than it could lead to knee issues in our athletes. Double leg squatting is a good starting point but having 2 fixed points of contact doesn’t challenge the hip musculature to the same degree as single leg work….and single leg unsupported to be specific.
Mike Boyle was the first strength coach that broke down single leg training into single leg supported and single leg unsupported. Single leg supported exercises is where you have 2 points of contact where one leg is performing the majority of the work. Examples are lunges, split squats, lateral squats, etc. Single leg unsupported work is where the body is supported on a single leg and the other leg is free (in the air). Examples of these exercises are single leg squats, single leg reaches, and pistol squats.
With basketball athletes and athletes with longer femurs it is imperative that single leg unsupported work be included to help develop the glutes to control the femur. Single leg squats to a box with a band above or below the knees is a great way to start and get the athlete to understand femoral control and the importance of it. You may need to start your taller athletes with a higher box and progressively move them down to a lower box as their strength and control improve.
We should all know the importance of single leg strength now, but if you are working with taller athletes make sure single leg unsupported work is included within your program.
What are other variations that you would include?
This blog post comes from Mike Boyle:
Here is an article I wrote for TMuscle.com that I think will help explain my stance on single-leg training.
I’ve advocated single-leg training over the years for a variety of reasons, which I summed up in an article for TMUSCLE back in 2007. In my view, single-leg training results in less back stress due to the reduced loads. And, although the phrase “functional training” is overused, single-leg training meets my definition.
It’s the application of functional anatomy to training. You do almost everything in sports in a split stance, or by pushing off one leg from a parallel stance, so it just makes sense to train your body that way.
Since I’ve already made that argument about single-leg training, there’s no need to rehash it here. Instead, I want to present an entirely new question: What if you could get more stress to your legs, build more useable strength, and potentially add more size by working around your back, which is often the weak link in bilateral exercises like squats?
This is what bodybuilders have been doing for decades. By bracing your back in the leg press, you can hit your leg extensors — your quadriceps — with far more load. That’s because the load doesn’t have to move through your back to get to your legs.
Now, before you think I’ve done a 180 and come to love the leg press, let me assure you that my opinion hasn’t changed. Yes, the machine allows bodybuilders to pile on the plates, but we now know that the back pays a price. It’s just a different price than the one lifters pay for using heavy loads in the squat. Instead of compressing the spine, the leg press causes a rounding of the back, which over time might create more damage.
Safety isn’t the only reason to avoid the leg press. The exercise has evolved into a kind of a circus act, done with the help of knee wraps, hands on thighs, and abysmal ranges of motion. Did you ever see that video of Pat Robertson, the 74-year-old televangelist, leg-pressing 2,000 pounds? If you took the exercise seriously before, that video surely curbed your enthusiasm.
All that said, when the goal is to build bigger, stronger legs, I still think it’s a good idea to target those muscles without having to place heavy loads on the spine. We just need to find a better way to do it.
Why the RFESS Is Your BFF
The rear-foot-elevated split squat, which I’ll abbreviate as RFESS, is usually called the Bulgarian split squat (BSS) here on TMUSCLE. In other venues it’s referred to as the Bulgarian lunge, despite the fact it didn’t originate in Bulgaria and isn’t a lunge.
The RFESS has numerous benefits. Beginners, for example, will develop balance and hip flexibility, along with strength, size, and the all-important ability to endure a high level of discomfort while training. But the really dramatic results come when more advanced lifters load up the exercise. You can apply huge weights to your leg muscles with limited spinal compression.
In fact, I think the loading capability of the RFESS is unmatched by any other exercise that primarily targets the leg extensors. And yes, I include the squat. When my trainers and I started using heavy RFESS as the primary lower-body exercise for our athletes, we found they couldn’t work both legs without taking a break in between.
A couple of quick technique points:
• Obviously, you can’t do the exercise without elevating your rear foot. An exercise bench works for most, but if you find the stretch to the quads and hip flexors of your elevated leg is too extreme or uncomfortable, switch to a slightly lower box or step. We find this necessary for some of our shorter lifters.
• The start of the exercise is a lot like a back squat, in that you position the bar on your shoulders in a squat rack, lift it off the supports, and take a step back. From there, lift one foot and place it on the bench behind you. You want to rest the top of your foot on the bench, even though it may be uncomfortable for you, especially if you’re used to doing this exercise with your toe on the bench. It may be easier for you to do it that way with lighter loads, but with heavier loads it’s not — the range of motion is longer, and your balance will be worse. Break the habit in week one.
• How deep should you go? We place an Airex pad or mat on the floor under the rear knee, and tell our athletes they have to touch the pad with their knee on each rep. This creates consistent depth, and also serves to cushion the knee. This is especially helpful when we’re testing our athletes’ strength on this exercise, which I’ll describe in the next section.
• As you would in a back squat or barbell lunge, you must keep your core tight and chest up. Core control is especially critical in the RFESS, as the elevated rear foot can create an unwanted back arch.
The Massachusetts Experiment
Recently I performed a little experiment on the hockey players I train, a very compliant group of athletes. I can’t call this true “research,” as we had no control group, but the results were so startling that I have to think they would stand up under true scientific scrutiny.
For most of our postseason training sessions, we did RFESS instead of traditional front or back squats. My goal initially was to test a hypothesis about back injury and back stress, but the conclusion went way beyond that.
After approximately six weeks of RFESS, we did a simple repetition-max test. Each guy took 50% of his one-rep max on the back squat and did as many RFESS reps as possible with each leg. Since we don’t do back squats in our program, we had to estimate each guy’s max by adding 15% to his 1RM in the front squat. And then, as I said, we used 50% of that number.
The estimated 1RMs for the back squat ranged from 290 to 460 pounds. So our test weights ranged from 145 to 230 pounds. My strongest athlete lifted 230 pounds 14 times with each leg. The weakest one did 14 reps on each leg with 145.
I drew two immediate conclusions:
First, if we had spent six weeks working on our back or front squats with equal focus and intensity, there’s no way in hell any of these guys could’ve lifted 5their estimated 1RMs 14 times.
The strongest guy, for example, had a very respectable 1RM of 405 in the front squat. That’s the number we used to extrapolate a max back squat of 460 pounds. Is there any drug-free training program on earth that could increase his strength to the point that he could lift either weight — his true 1RM in the front squat or estimated max in the back squat — 14 times? And to make it comparable, he’d need to do two sets of 14 reps, since he did 14 RFESS reps with 230 pounds with each leg.
If he got to the point where he could back squat 460 for 14 reps, it would imply a 1RM of 675 pounds. Nothing’s impossible, but this scenario comes pretty close.
That brings us to point number two, which is far more important: The experiment showed that the athletes’ legs could handle far more weight than their backs were capable of transmitting. This suggests that the back is the weak link in squatting. Bypass the back, and your legs can handle much heavier weights.
Backing It Up
To me, the results of my experiment make intuitive sense. What gets injured most often in squatting? The back. So how do you train your legs with heavier loads, with the goal of increasing strength and size? Bypass the back.
You may wonder why this conclusion isn’t completely obvious and uncontroversial.
For starters, old-school gym culture puts the back squat on a pedestal. You can’t convince traditionalists that there’s a more effective way to train the lower body for strength and size, and they won’t experiment to figure it out for themselves
.
Second, the RFESS has a specific niche in training programs. It’s an exercise you do for fat loss, or for muscular conditioning, usually while holding dumbbells at arm’s length. I can’t recall any popular book or magazine recommending the exercise with a barbell, using heavy weights for low reps.
Third, I think the exercise is just awkward enough to discourage lifters from pushing themselves to better performance. That’s why it’s used in fat-loss programs — it feels like a punishment for needing a fat-loss program in the first place. Lifters who’ve spent years mastering the back squat, followed by months or years with the front squat after coaches like me talked them into switching, don’t want to spend a few weeks getting comfortable with the RFESS.
Finally, I think it’s difficult for the guy I just mentioned, the guy who’s worked like a slave to build bilateral strength in the squat, to work with half his max in a single-leg exercise. I can relate; I wouldn’t have considered it back in my powerlifting days. But now that my only goal is to help my athletes get bigger and stronger for their sport, it’s a lot easier to be open-minded about better ways to accomplish those goals.
So try looking at it through my eyes: If there’s a way to get better results with half the weight by training one leg at a time, shouldn’t you at least give it a shot? Especially when you consider the back-sparing effects of using lighter loads?
It’s like someone offering you 50% off on your next major purchase. Sounds like a great deal to me.
