What you are paying for in a private

Attention and adaptation. A teacher watching one body can adjust spring load, foot position and range in real time, and can work around an injury in a way a group format cannot. For the first six to ten sessions, or after any injury, that is worth a great deal.

You are also paying for diagnosis. Most people have an asymmetry or restriction they are unaware of, and it will not surface in a group class.

What group classes do better

Cost per session, obviously — typically a third to a fifth of a private. But also consistency: a scheduled class with other people attached to it produces far better attendance than an open-ended intention to train.

Group classes also expose you to a wider variety of programming than a single teacher’s private sequence usually does.

A sensible sequence

Start with three to six privates to learn the machine and get your body assessed. Move to group classes for volume and consistency. Return to a private every couple of months, or whenever something starts hurting or stops progressing.

That pattern costs far less than privates throughout and produces better results than group classes alone.
