Infinite Series (33)

The BUILT Strength Infinite Series is a plate-loaded machine line built around iso-lateral presses, rows, and lower-body stations for commercial floors and serious home gyms. Popular pieces include the Orbital Row, the Smith Tower Multi-Press (iso-lateral arms with a flat, incline, and upright bench), the Pro Squat, a Linear Hack Squat, the 3D Glute, an Iso-Lateral Kneeling Leg Curl, T-Bar Rows, a Standing Lateral Raise, and a Lat Pullover. Plate loading means no stack ceiling, so you can keep progressing as long as you have plates.

What does iso-lateral mean on Infinite Series machines?

Each arm or leg moves and loads independently, so your stronger side cannot take over. That helps build balanced strength and lets you train one side at a time.

Infinite Series or OG Series: which should I choose?

Both are plate loaded. Infinite leans toward iso-lateral upper-body and specialty stations, while the OG Series includes the leg press, pendulum squat, V squat, and belt squat. Many rooms mix the two.
