RFESS MFE (Rear Foot Elevated Split Squats Made for Everyone)
Today’s guest post comes our way from Montreal based strength coach, Rich Thaw. I had the pleasure of meeting Rich several times a few years ago while he was here in Boston interning for Mike Boyle Strength and Conditioning.
We all know the importance of single leg work, and it’s probably a safe assumption to say that it’s something we all love to hate.
While I won’t sit here and say I hate single leg work as much as I hate Jar Jar Binks, I have no qualms putting it in the same breath as poodles or people who don’t turn right on red.
I’m not impervious to the hate. But I still do it.
That said, single leg work is a staple at Cressey Performance and if there’s one exercise which makes our athletes belly ache the most it’s the RFESS, or more popularly known as the Bulgarian Split Squat.
In this post Rich breaks down some technique flaws as well as offers some different variations to try.
Enjoy! – TG
Bulgarian Split Squats have been around for generations (apparently) but only recently have been thrust into the limelight. In recent years Bulgarian Split Squats have been making headlines everywhere from magazines to online publications and even on YouTube (note the sarcasm…everything makes it to Youtube)
Bulgarian Split Squats were outrageously foreign to me until the summer of ’09 when I started my internship at Mike Boyle Strength and Conditioning (MBSC). Although I had seen them before and used them a few times, I had not really exploited them to their full potential.
Long story short, after chasing a 315lb front squat for several months leading up to the internship, I decided to abandon the all-mighty lift in exchange for RFESS.
Fast forward 3 months and back to Montreal where I returned post-internship, I decided to re-attempt front squatting 315lbs.
The most recent experience yielded a mediocre 280lbs for 3 reps.
This time was different, I un-racked the bar and it felt really freakin’ heavy. I sat back and lowered myself to the 12’ box I had as a depth gauge, and then stood up without much difficulty…hmmm.
I decided to go for another, and then a 3rd. Racking the bar I thought to myself; “I have one more in me”. So I took a breath and gave’er for another.
I just front squatted 315lbs for 3 + 1 reps up from 280lbs for 3 reps only 3 months ago. That’s a 35lb increase and a rep to boot in a little under 3 months. WTF!?
What The Heck Is A RFESS And Where Can I Get Some?
Simply put, a RFESS (Rear Foot Elevated Split Squat) is a Bulgarian Split Squat, only with a less cool and more straightforward name.
Besides, I doubt the Bulgarians made up this exercise.
Note: I’m still awaiting conformation from The Bulgarian Government).
Lets start things with demonstration of the difference between a “good” RFESS and a bad one.
RFESS are a tricky beast, but when done correctly, in my opinion, they’re one of the best exercises which gives you the most bang for your training buck.
RFESS Are (Not) Made For You
They have huge benefits if used and loaded correctly, but correctly is a pretty vague term.
However, they’re not the best exercise for everyone – particularly if you’re rocking a solid anterior pelvic tilt (APT).
(Hyper) lordotic individuals usually develop these patterns as a result of breathing mechanics as well as a number of tight and weak muscles most likely set forth by sport, and repetitive, aberrant habits.
Lordotic people usually have a diaphragm that is ‘stuck’, tight lats, Quadratus Laborum (QL), Psoas, and Rectus Femorus, which are also tight/overactive – most notably understood under Janda’s Lower Cross Syndrome.
If You Present with Low Back Pain
The rear foot elevated position sets your pelvis up in a mildly compromised position. If, for example, the surrounding hip musculature is tight, the innominate bone (the hip bone on one side) of the leg that is on the bench will anteriorly rotate while the sacrum and innominate bone of the driving leg stays neutral.
This is not a great loading pattern.
What’s more, if you’re really tight the sacrum could be rotated as well…also not a pattern you want to load.
During a seminar I took with Dr. Stuart McGill back in April of 2013, he mentioned the increase in popularity of sacroiliac (SI) pain resulting from single leg training. All the more reason to make sure your core is working flawlessly.
The idea is that you don’t rely on joints for stability but rely on the surrounding musculature for stability. As it relates to some people, their back pain can very likely be related to some sort of compensation pattern and/or tight muscle(s).
If Your Buns Aren’t Made Of Steel
At CoreXcellence it is of the utmost importance that by the time we progress to RFESS in the program, our athletes and everyday clients have effective and efficient glutei function.
To get buns of steel you need your butt to fire first in hip extension, then the Adductor Magnus, hamstring, and lastly the lower back at the extreme end range. To effectively determine if that is the case on your end, here’s a quick test:
If You Can’t Lock It Down
The ‘proper’ way to do a deadlift used to be to bend down, arch the back and pick up the bar. But no longer.
You need to be able to maintain a rigid torso throughout any movement and keep the ribs locked down.
Think of maintaining the distance between the ribs and the pubic bone the same as when you are standing braced to when you are bent over in a hip hinge (deadlift pattern).
It’s impossible to contract a stretched muscle, and by arching your back (shown in the 1st photo) your entire mid-section is stretched.
That leaves one of two places for a trainee to gain stability:
1) The powerful lats, and 2) The vertebrae, sacrum and sacro-iliac joints. Again, not a pattern you want to load.
The inability to keep the distance between the ribs and pubic bone consistent during a split squat, reverse lunge and a slideboard lunge, in that order, throws up a major red flag.
Sorry, no RFESS for you chief.
RFESS Progression Checklist
#1 – Split Squat
#2 – Reverse Lunge
#3 – Slideboard Lunge
#4 – RFESS
The Set-Up
Grab yourself a good old-fashioned bench. Prop the shoelaces of your left foot on the bench then lower that knee to the ground. You’ll be in a half-kneeling position.
The Right heel should be slightly behind your knee.
Note: This is a great position to assess if you can maintain neutrality in your hips or if you are rotated. If you can get and maintain a neutral pelvis, you’re cleared for takeoff.
At the bottom of the exercise your right femur should be just slightly below parallel with the ground.
If you have access to a Single Leg Squat Stand you’re golden.
It’s set up for RFESS specifically so no tinkering required. It’s much more comfortable on the ankle than a bench. Benches pinch your ankle at times.
If you don’t have access to a Single Leg Squat Stand you can always jimmy a bench to replicate it by attaching a half-roller onto the top with some mini-bands.
Load ‘er up
There are a few ways of loading RFESS. The go-to loading pattern I use with clients and athletes is always the dumbbell goblet. Once they master the goblet RFESS, then they can progress to any number of variations.
Here are a few I use quite frequently:
1. Dumbbell or Kettlebell Goblet
2. Bilateral Dumbbell
3. 1-Arm Kettlebell
The bell usually touches the floor at the exact moment when you reach optimal depth, usually.
4. Front Racked Barbell
5. Back Squat Barbell
My beef with back loading
While it may work wonders for some, I firmly believe that by loading the bar on your back only further reinforces an arched back, stretched abdominals, and recruits the lats & QL’s to act as stabilizers rather than the core.
Sure the first rep or so will look decent, but decent isn’t good enough for the first few reps. Every rep should be flawless. Your last rep should always be your last good rep. It’s also a lot harder to coach this pattern compared to the front racked position because of the pattern it reinforces.
Wrap Up
While there are more than a few contraindications and compensations to look out for in a RFESS, the same principle applies for every exercise.
A stable torso, ample mobility, stability and flexibility are all required to reap the rewards of this exercise with none of the risk. It all comes down to progression. RFESS are an advanced exercise and should be treated as such.
Give yourself a few weeks to perfect a flawless Split Squat, Reverse Lunge and then Slideboard Lunge and then RFESS will be made for you!

Great post. One of the gems I will be putting to use right away is "keeping the ribs locked down". I have had very good IAP except in the starting position of the DL, which has been causing me problems early in the lift. Essentially trying to contract a lengthened muscle. This offers me (and people I train with) an approach to correcting that. Awesome.January 9, 2014 at 10:44 am |
Rich
You can also try cueing your clients to completely exhale to the point where their ribs come down and abs contract. This will give them the body awareness of what it feels like to have both the ribs locked down and transverse abdominis/internal obliques contracted. - Thanks man, glad I could help!April 25, 2014 at 2:31 pm |

Rich, Great post! The RFESS is my favorite lower body exercise, but recently I've been having issues with a tight right hip, which you explained as a warning sign in this post. I notice that when it is noticeably tight, it affects my depth when my right leg is back on the bench and left leg down. I can't go as low, I wobble more, and it feels awkward compared to the other side which is smooth as butter. I have less IR on my right leg, and obviously can't achieve the same hip extension on my right side. Needless to say I know I have an issue if I continue with the RFESS. I follow a lot of Kelly Starrett's mWOD's so I am assuming that if I have a tight right hip, I can do some anterior quad and hip foam rolling, some hip opener stretches, and that should help -- but I was just curious what sort of protocol you prescribe for tight hips? Especially if there is an asymmetry between both sides. Thanks! ChrisJanuary 9, 2014 at 10:55 am |

Ever since we've started to really incorporate principles from PRI (Postural Restoration Institute) we've realized that some of the band distraction stretches could stretch the capsule and ligaments too much. What may present as a hip flexor tightness could be really related to breathing patterns. Since the diaphragm overlaps the psoas, we've been working with diaphragm release and breathing exercises from PRI to effectively release the diaphragm which in turn releases the psoas (a major hip flexor). I wrote something that may give you some insight into asymmetries with the hips and breathing. I'm going to write a follow up shortly...

Please, just call it the Bulgarian Split Squat. Yes it isn't descriptive, but it is the commonly accepted name by everyone not associated with Mike Boyle.January 9, 2014 at 3:04 pm |

Another option for RFESS without the single leg stand is to buy one of these: http://www.homedepot.com/p/Husky-300-lb-36-in-Zinc-Plated-Steel-Hang-All-18390/202305503# for 7 bucks at the ole home depot, and click the carabiner over a bar put your "top" foot in the loop. works pretty well.January 9, 2014 at 3:10 pm |
Rich
Not a bad idea! Thanks JohnApril 25, 2014 at 2:44 pm |

Been playing with this exercise for the last couple months, lately as an A1. Goal is to get up to 225 for reps via anterior loading. At 205 right now. What I've noticed is the stand setup mentioned by Thaw is essential for lifting heavier weights. It allows me to push back and down into the "bench," thus better engaging the glutes on the trailing leg than the traditional bench setup. RSJanuary 12, 2014 at 7:33 pm |
