"I Did Bulgarian Split Squats Every Day for 28 Days—Here's What Happened to My Body"
One WH editor put her quads and glutes to the test.

Some exercises earn their reputation through results. The Bulgarian split squat is one of them — and also, arguably, the most universally dreaded move in any leg day lineup. One writer decided to stop avoiding it and committed to 28 consecutive days of the exercise, documenting exactly what changed. According to Women's Health Magazine, the findings were more significant than expected.
For the uninitiated: a Bulgarian split squat is a single-leg squat performed with the back foot elevated on a bench or box. It sounds contained. It is not. PT and Women's Health Deputy Social Manager Issy Shury breaks down why it hits so hard: "It isolates one leg at a time, so there's nowhere to hide. You can't compensate with your stronger side, your balance is constantly challenged, and the time under tension builds quickly." Classified as both a dynamic stretch and a strength exercise, it works the glutes, quads, hamstrings, calves, and adductors simultaneously — while demanding serious core engagement just to keep you upright. It also delivers a deep hip flexor stretch on the rear leg, making it quietly invaluable for anyone who sits for most of the day.
What 28 Days Actually Did
The protocol was straightforward: three sets of eight reps per leg, alternating between glute-focused and quad-focused positioning on different days, with gradual dumbbell progression from bodyweight up to 6–10kg. The first revelation wasn't muscle soreness — it was asymmetry. The left leg wobbled noticeably more than the right, exposing a long-standing stability imbalance linked to an old Achilles tear. By day 28, both ankle and knee stability had measurably improved on the weaker side. Core engagement became automatic rather than effortful, and a treadmill run mid-challenge confirmed what the research promises: stronger, more powerful strides. Perhaps the biggest surprise was improved hip mobility — real, noticeable flexibility gains in an area that had been chronically tight for years.
Form is everything here. Shury recommends using two dumbbells for stability, keeping the front heel planted, and bracing the core like you're "absorbing a punch" on the way down. Want more quad burn? Keep your torso upright and let the front knee track slightly past the toe. Chasing glutes? Add a subtle forward hip hinge at the bottom. Either way, drive back up through the heel and midfoot — that's where the real work happens.
The Bulgarian split squat is uncomfortable precisely because it's effective: no dominant side to lean on, no sloppy compensation, just one leg doing the work it was always supposed to do. Add it to your rotation now, or keep wondering why one side of your body is quietly running the show.
