You do not have to be strong to start.
You get strong by starting.
Moving with your body as it changes, at a pace that respects it.
Rebuilding deep core and steady strength on your own timeline.
Returning to movement with care, never rushing the recovery.
Easing back in after a long pause, with zero judgment.
Staying strong for the lifting, carrying, and chasing of real life.
Crystal Merkel did not find this work in a polished studio. She found it through her own body, across pregnancy, surgeries, and loss, learning how to come back to strength when starting over felt impossible.
A fitness coach and HIIT instructor with a Foundation Training background, she built Ocotillo Core Collective around a simple truth she lived. Caregivers do not need to disappear into a gym to get strong. They need movement that fits real life, welcomes their kids, and meets them exactly where they are.
“Strength is not something you are given back. It is something you grow, one steady season at a time, like the ocotillo.”
Crystal Merkel
The method is shaped alongside Alli, a pediatric occupational therapist. Her grounding in anatomy, child development, and play is why a toddler clambering through a session is not a distraction. It is part of how the work actually gets done.
Sessions weave these together into something that feels less like training and more like play. And the children are not on the sidelines. They are part of the workout, climbing, counting, and moving right alongside you.
The lifting, carrying, and rising that real days are made of.
Rebuilding from the center out, breath and brace working together.
Joints that move freely so strength has somewhere to go.
Steadying the nervous system, the quiet engine under every lift.
Squat, crawl, reach, climb. The way bodies were built to move.
Strength holds longer when it is shared. We move in groups, learn names, and keep showing up for one another.
The work hides inside the fun. Games, challenges, and kids underfoot turn a workout into something you look forward to.
Like the ocotillo, which greens with the rain and waits out the dry, you learn to adapt to every season and grow through it.
“I came to a free Happy Javelinas workout with my 18-month-old on my hip, sure I would have to leave early. Instead he played in the grass while I actually moved, and a circle of moms cheered me on. I have not missed a week since.”
Eight weeks postpartum, I did not trust my own core. Crystal met me exactly there and rebuilt it with me, never rushing. I feel like myself in my body again.
After my surgery I assumed working out was off the table for a long while. Every movement was scaled to what I could do that day. It felt like care, not a class.
