A member came to us last year — 34, runs half marathons, trains three days a week at our Folsom studio — and mentioned almost in passing that she leaks a little during heavy back squats and box jumps, always worse the week before her period. She’d assumed it was just part of being a woman who trains hard, something to manage with a pad and a shrug. It’s not. That conversation is where personal training for pelvic floor dysfunction actually starts for a lot of our clients: not with a diagnosis, but with a symptom they’d normalized for years.
Pelvic floor dysfunction in active women is common, treatable, and closely tied to how you train across your cycle, not just what exercises you do. This is the approach our coaches use with clients dealing with leaking, heaviness, or pelvic pain tied to training — built around load management, breath mechanics, and programming that shifts with hormonal phase instead of ignoring it.
What Pelvic Floor Dysfunction Actually Looks Like in Active Women
Pelvic floor dysfunction isn’t one condition. It covers stress urinary incontinence (leaking during effort — a heavy lift, a sneeze, a jump), pelvic heaviness or pressure, and sometimes pain during specific movements. In active women, it shows up most during high-impact or high-intra-abdominal-pressure activity: sprinting, jump rope, heavy squats and deadlifts, double-unders.
This is more common in athletic populations than most people expect. Research reviewed by pelvic floor physiotherapist and researcher Kari Bo has found stress urinary incontinence rates ranging from roughly 25% to as high as 80% in high-impact sports like trampoline and gymnastics, depending on the population studied. Running and CrossFit-style training land in a meaningful range too. The common thread isn’t weakness in the way people assume — it’s often a coordination problem between the deep core, diaphragm, and pelvic floor under load, not a lack of effort in kegels.
How Your Menstrual Cycle Changes Load Tolerance and Pelvic Floor Function
A typical 28-day cycle isn’t hormonally flat, and neither is your training response. Estrogen rises through the follicular phase (roughly days 6-13), which for most women lines up with better strength output and more stable joint mechanics. Around ovulation, rising estrogen is associated with increased ligament laxity — part of why some research on ACL injury risk has focused on this window. Progesterone then dominates the luteal phase (roughly days 15-28), often bringing increased body temperature, bloating, and for some women, more noticeable pelvic floor symptoms.
A well-cited review by exercise physiologist Xanne Janse de Jonge summarized decades of research on this and found meaningful, if individually variable, effects of cycle phase on strength, endurance, and injury risk. That variability is the key point — this isn’t a reason to train less, it’s a reason to track your own pattern and adjust specifics rather than run the identical program every single week regardless of what your body is telling you.
The Coaching Protocol We Use: Programming Core and Pelvic Floor Work by Cycle Phase
We don’t hand every client dealing with pelvic floor symptoms the same three exercises. But there’s a structure we lean on, adjusted to the individual’s symptom pattern and where they are in their cycle:
- Follicular phase (roughly days 6-13): Heavier compound work fits well here for most women — back squat 4×5 at 75-80% of 1RM, deadlift 3×5, hip thrust 4×8 at moderate-heavy load, paired with breath-to-brace coaching on every heavy set.
- Ovulation window (around day 14): We keep loads similar but pay closer attention to landing mechanics and control on plyometric work, given the ligament laxity research noted above — fewer max-effort jumps, more controlled tempo work.
- Luteal phase (roughly days 15-28): We shift emphasis toward isometric and anti-rotation core work — front plank 3×30-45 seconds, side plank 3×20 seconds per side, dead bug 3×10 per side, Pallof press 3×10 per side — while keeping compound lifts at a moderate load rather than pushing new maxes.
- Menstrual phase (roughly days 1-5): For clients with cramping or increased symptoms, we lower impact volume and prioritize diaphragmatic breathing and mobility; clients without significant symptoms often train close to normal, and we let their reporting guide the call, not a blanket rule.
This structure overlaps closely with the sequencing we use in our 4-day core stability training plan, adapted here specifically for symptom tracking and cycle phase rather than general mobility goals.
Coaching Cues and Form Corrections We Actually Use in the Gym
The single biggest correction we make with clients dealing with leaking under load is breath timing. A lot of people hold their breath and bear down through the hardest part of a heavy rep — a Valsalva pattern that spikes intra-abdominal pressure straight down onto the pelvic floor. We teach a breath-to-brace pattern instead: inhale for about 4 seconds, expanding the ribcage 360 degrees rather than just the belly, then exhale for 6-8 seconds through the sticking point of the lift while actively engaging the deep core and pelvic floor together.
We practice this away from load first — 2 sets of 8-10 breaths lying down, hand on ribs, hand on lower belly — before we ever load it into a squat or deadlift. Clients often need several sessions to feel the coordination before it holds up under a heavy set, and that’s expected, not a sign something’s wrong. This same breath coordination work shows up in how we approach clients managing low back stability and chronic lower back pain, since the deep core and pelvic floor function as one pressure system, not separate parts.
Glute strength matters here too, more than most people expect. Weak or under-firing glutes shift more of the stabilization job onto the lower back and pelvic floor during squats, deadlifts, and running. We frequently pair pelvic floor coaching with dedicated glute activation work — banded lateral walks, hip thrusts, single-leg glute bridges — to take pressure off the system that’s already working overtime.
Building This Into a Real Week at GForce
Here’s what this looks like for a client training three days a week with us, tracking her cycle on her phone:
- Monday (follicular, day 8): Squat 4×5 @ 78%, hip thrust 4×8, breath-to-brace drilled on every top set
- Wednesday (follicular, day 10): Deadlift 3×5, single-leg glute bridge 3×10/side, Pallof press 3×10/side
- Friday (approaching ovulation, day 13): Moderate-load full-body circuit, controlled tempo box step-ups instead of jump work, core finisher of dead bugs and side planks
Two weeks later, in the luteal phase, the same three days shift toward moderate loads and more isometric core volume, with impact work trimmed if she’s reporting symptoms. Nothing here requires stopping training — it requires a coach who’s asking the right questions and adjusting the plan instead of running the same spreadsheet every week regardless of what’s actually happening in her body. This is also where under-fueling becomes relevant: active women training hard without adequate intake can develop menstrual irregularities described in sports medicine research as Relative Energy Deficiency in Sport, which can worsen the exact symptoms we’re trying to coach around. We ask about training volume and eating patterns together for this reason, not just prescribe more exercises.
For clients further along — postpartum, over 40, or managing more established pelvic floor dysfunction — we build on the same foundation covered in our pelvic floor health program for active women, adjusting intensity and progression to where they are physically.
Your Next Step
If you’ve been leaking, feeling pelvic heaviness, or quietly avoiding certain lifts or sprint work because of it, that’s worth an actual conversation with a coach, not another few months of working around it silently. Book a free intro session at GForce and tell your coach specifically what you’re noticing and when in your cycle it happens — that detail changes how we build your first four weeks, and it’s the difference between generic core work and a plan that actually addresses what’s going on.
