Bikini Build is live. Winter is for building. The launch challenge is open. Get in early.
Bikini Build

Build the shape.
Then shred it down.

You build before you shred, always. Bikini Build is where ALTER starts: a winter block of glute and muscle growth, adding weight to the bar, laying the foundation you will lean down to in spring. Train with the cohort, chase your numbers up, and build the shape first.

The launch challenge · Glute & muscle growth · Included with membership · 3 days free

This is the one that starts you.

You cannot shred down to something you never built. Bikini Build comes first on purpose: a whole community starting the build together, so you add real size and strength before the Summer Shred leans it out in spring.

How Bikini Build works

Four steps, one build.

  1. 01

    Join and lock your spot

    Get in with the founding cohort for founding pricing, and your three free days start the moment you download.

  2. 02

    Answer eleven questions

    Your goal, your equipment, your experience. ALTER builds your training and your macros around your answers. No guessing on day one.

  3. 03

    Train with the cohort

    Follow the plan, log every session, watch the weight on the bar climb. The whole app is pushing the same eight weeks with you.

  4. 04

    Build the foundation

    Add weight, add size, add strength. The biggest transformation, measured by the work you did and the sessions you showed up for, takes the prize.
