Crystal Merkel
Meet your coach
Ocotillo Core Collective grew out of Crystal Merkel's own story. Through pregnancy, surgeries, and loss, she learned how to rebuild a capable body slowly, gently, and with grace. That lived experience shapes every session she leads.
As a fitness coach and HIIT instructor with a background in Foundation Training, Crystal blends practical strength with deep care. She believes movement should adapt to your life, welcome your children, and feel a lot more like play than punishment.
With influence from Alli, pediatric occupational therapist
Alli brings an expert lens on anatomy, child development, and play, so the toddler-inspired movements are genuinely good for growing bodies and grown-up ones alike.
The approach
Functional strength, deep core, mobility, breathwork, and play. Scaled to you, set outdoors, and built to feel good.
Movements that carry over to lifting toddlers, car seats, groceries, and life.
Reconnect and rebuild the core that pregnancy and surgery change, from the inside out.
Open up hips, spine, and shoulders so your body feels easy to live in again.
Breathe with intention to steady your nervous system and power every movement.
Crawl, climb, balance, and play. The instincts kids never lost are great training.
What we stand on
We move together. The people beside you in the park become the ones who cheer you on, swap snacks, and hold space for your hard days.
Strength does not have to be serious. When movement feels like play, you keep coming back, and your kids learn that bodies are for joy.
Like the ocotillo, you adapt to every season. It looks bare and waits, then bursts into bloom after the rain. You are built to do the same.
Real movement, real families, real life. Here is what it feels like to show up.
I came back six weeks postpartum, terrified and out of breath. Crystal met me exactly where I was and let my daughter nap in the stroller beside us. I feel like myself again.
The Happy Javelinas workout is the highlight of our week. My toddler thinks it is a playground and I am quietly getting stronger. It never feels like a gym.
After my surgery I assumed exercise was off the table for a while. The workshop scaled everything down and built me back up. No pressure, just patience and good people.
Where we meet you
Happy Javelinas workouts move from park to park so a session is never far from home. Personal training and the workshop come to your corner of the valley too.
