About
Behind the barbell — Lemar Williams
At Adamantium Fitness, precision beats intensity. Every program begins with assessment, not assumption — mapping movement quality, training history, and daily load before a single rep is prescribed.
The work centers on targeted weight loss, lean muscle hypertrophy, and corrective exercise protocols that repair imbalances, restore joint mechanics, and unlock output that lasts far beyond a single training block. Progress is tracked, not guessed: composition scans, strength benchmarks, and weekly load reviews keep every session accountable to a number.
Coaching runs in-person on a private Midtown Manhattan floor and virtually worldwide, with the same standard of structure and accountability — and the same apparel line, Adamantium Athletic Apparel, engineered for the athletes who train in it.

Questions & Answers
Everything You Need To Know Before Starting
Details on training location, remote coaching structure, corrective work, and apparel access.
All in-person sessions take place at 54 W. 39th Street, 3rd Floor, New York, NY 10018 — a private Midtown Manhattan training floor with full strength and conditioning equipment.
You receive a custom program delivered digitally, scheduled video check-ins for form review, and direct messaging access for accountability. Sessions can be run live or asynchronously depending on your schedule.
Corrective exercise targets movement restrictions, muscular imbalances, and compensation patterns. If you experience recurring joint discomfort, plateaued lifts, or asymmetry, it becomes the fastest route back to progress.
