Hands-on coaching during a private session
my approach

Built around how your body moves

No mirrors-and-ego. Just alignment-first coaching from a Best of Las Vegas instructor who trains every body, first-timers to athletes. You are never left to guess: we move with you, adjusting alignment, breath, and spring load in real time.

Alignment first

Neutral spine, pelvic floor, dynamic alignment. We build the foundation before we add load, so you get stronger without getting hurt.

Real reformers

Spring-based resistance that supports beginners and challenges pros. More core, more control, more length than mat alone.

Coached, not crowded

Small classes and true 1:1 sessions. Your instructor knows your name, your injuries, and your goals by week two.

Osi Leeb, founder and lead instructor
oh hey,

I'm Osi, and I'm going to change how your body moves forever.

Military discipline and a Best of Las Vegas gold streak, all in service of one belief: every body can move better.

I built Osi Body Fit on a simple promise, train the person in front of you, not a generic program. Pilates by Osi Body Fit extends that standard into a dedicated reformer studio: alignment-first, coach-led, and built for real results.

What everyone asks first

Pilates by Osi Body Fit, 5.0 stars across 139 reviews, Best of Las Vegas Gold 2022–2025.

Group reformer classes are $38 drop-in, with packs from $129 and unlimited from $259/mo. Private 1:1 sessions start at $95. Your first class here is always free. See pricing.

Absolutely, low-impact and scalable. Beginners start with neutral spine, breath control, and core stability, then progress to the reformer.

Mat builds raw core strength; the reformer adds spring resistance with more support for beginners and more load for pros. Most start on the reformer.

Right here in Summerlin. Our private 1:1 sessions are built for rehab, prenatal, postpartum, and athletes.
