Add-on for the ASCENT platform. Boosters stack onto the ASCENT — they don’t work standalone. If you don’t own one yet, get the ASCENT first.

How the boost stacks 3 angle settings

Each booster adds incremental height to the elevated end of the ASCENT. One booster per side gives a meaningful step up; two per side hits the steepest angle the platform supports. Use the 4-pack to keep two configurations ready — one stack for warm-ups, one for working sets.
