The economics cross over quickly

At $28 a class, two classes a week is roughly $2,900 a year. A home reformer at $2,500 pays for itself inside a year at that frequency and costs nothing thereafter beyond maintenance.

Below one class a week, the studio is cheaper and better. The crossover is around two classes a week sustained over a year.

What you lose training at home

Feedback, most importantly. Nobody sees your compensations, and video instruction cannot. Over months, unobserved compensations become embedded patterns that are harder to correct than they were to prevent.

You also lose the accountability of a scheduled class, which for many people is the difference between training and intending to.

What you gain

Convenience, which translates directly into frequency. A fifteen-minute session before work is possible at home and not at a studio, and those short sessions add up substantially over a year.

You also get to work at your own pace, repeat what you need, and skip what you do not.

The pattern that works best

Learn at a studio for three to six months, buy a machine, keep one studio class a fortnight for feedback, and do the rest at home.

That keeps the correction loop open while capturing most of the convenience and cost benefit.
