What Is Small Group Personal Training?
Small group bridges the gap — the coaching and safety of personal training, with the energy of training together.
Everyone begins with a free intro, a full assessment, and the Foundations On-Ramp — private sessions that teach you the movements your program is built on and clear you for group training.
Each session runs the Strength Affect Method as a shared workout — scaled to your level and modified for your body, every time.
Four people, one coach, eyes on every set. Small enough that your coach knows your history, your limits, and your goals.
Same InBody scans, same force-plate retests, same proof. Group training doesn't mean guessing.
Who It's For
You want real coaching — not an instructor with a microphone and a room of thirty.
You train better with a few people around you — energy, accountability, and someone who notices when you don't show up.
You want the full Strength Affect Method — assessment, coaching, and measured progress — at a fraction of the cost of one-on-one.
You're willing to earn your spot — everyone starts with a one-on-one on-ramp before joining the group.
Small Group Personal Training
Small group personal training is exactly what it says — personal training. Don't expect 20 people, one coach, a microphone, and mindless exercises. This is real strength training with a real strength coach — where we prescribe exercise variations, periodize your training, and coach everyone in the session.

Questions? Answered.
No — the on-ramp exists exactly so you never walk into a group unprepared. You start one-on-one with an assessment and foundational sessions, and you join the group when you're ready.
Your assessment and on-ramp map it before you ever train in the group — and your coach prescribes variations and modifies your session in real time.
Never more than four. Small enough that your coach sees every set.
Yes — many clients do both, or move between them as their goals change. We'll recommend the right mix at your free intro.
