Steelset Performance

Steelset Performance is one app for strength training: gyms use it to run programs, classes, and memberships, and athletes without a gym get a 4-week plan written by AI that changes as they train.

Getting ready for its first gyms.

Steelset's gym panel: the Overview, with this week's bookings, today's classes, and monthly income.Steelset's phone app: today's workout, with each exercise's sets and reps, and Continue workout.

Who it's for

Gym owners and managers

“I want members to pay on time, book without calling me, and stay in the program, without three different apps.”

Trainers

“I want to write a program once, see who's actually doing it, and know when someone needs a word.”

Gym athletes

“I want today's workout in my hand, a place to log what I lifted, and an easy way to book a class.”

Athletes training on their own

“I want a real program that changes with how my training is going, without hiring a coach.”

What it solves

  • Programs on paper or in a spreadsheet get lost and never come back filled in. In Steelset the athlete has the program on their phone and logs every set, and the trainer sees what was done.
  • Missed sessions go unnoticed until the athlete quits. Trainers get an alert when an athlete misses workouts or falls short of the program.
  • Chasing payments. Members pay by card into the gym's own Stripe account, and a failed payment gives the member a short grace period before booking stops.
  • Phone calls and texts to book a class. Athletes book up to a week ahead, join a waitlist when a class is full, and are booked automatically when a place opens.
  • Late cancels and no-shows. The gym sets its own late-cancel fee, and the app charges it.

Features

For gym owners and managers

  • Memberships and payments: set your membership plans and prices. Members pay by card straight into your own Stripe account, and you can record payments made at the desk.
  • Class schedule: classes with a set number of places, waitlists, and a weekly booking limit for each membership. Cancel one class or a whole day, and booked athletes are told.
  • Late-cancel fees: your own policy, charged automatically, with "Mark paid" and "Waive" when you need them.
  • Overview: today's classes, the week ahead, what needs attention, and your income over the last 12 months.
  • Bring your people over: import athletes and classes from a spreadsheet.
  • Your gym's look: your logo and your color in the app your athletes use.

For trainers

  • Programs: write programs from an exercise library with demo videos, start from your gym's templates, or import one from a spreadsheet.
  • Alerts: a short list of athletes who need attention, and a daily summary of everyone else.
  • Class rosters: check athletes in, add walk-ins, and see who's on the waitlist.
Steelset's program editor: Day 1's exercises, each with its sets and reps for weeks 1 to 4.

  • Show me: a demo video for each exercise.
  • Book: classes up to a week ahead, with waitlists.
  • History: every finished workout, by month.
  • Membership: your plan, your next payment, and your card, all in the app.
