CRT Full Body is Ninety9 Degrees’ signature Controlled Resistance Training method: a full-body experience designed to build adaptive strength, muscular endurance, and deep core stability through slow, intentional movement under constant tension.

Performed on the Mega-Reformer, every sequence is engineered to eliminate momentum and maximize muscular engagement. Movements are intentionally controlled to challenge stability, alignment, and neuromuscular coordination while maintaining continuous resistance from start to finish.

This method trains the body to sustain precision and output under fatigue; developing strength that adapts, stabilizes, and performs efficiently inside the body’s optimal internal performance zone: 99°.

Expect extended time under tension, strategic resistance changes, and full-body programming that strengthens both large muscle groups and the smaller stabilizing systems that support posture, control, and longevity.

Dim lighting, immersive music, and focused instruction create an environment that pulls attention inward. Instructors provide biomechanics-driven cueing, hands-on corrections, and intentional pacing to ensure every movement is controlled, effective, and deeply felt.

Low-impact. High-intensity. Zero momentum. Maximum shake.

Upper Body & Core is a targeted format designed to sculpt the upper body while reinforcing deep core integrity through precise, controlled resistance.

Movements prioritize shoulder stabilization, spinal alignment, and sustained abdominal engagement, building functional strength and postural endurance without momentum.

Training on the Megaformer allows for isolation without compromise. Prolonged time under tension, eccentric loading, and micro-isometric holds activate slow-twitch fibers responsible for endurance, definition, and joint support.

The environment is focused and intentional. Instructors provide real-time correction and detailed cueing to refine control, alignment, and output.

This format strengthens the upper body and core as an integrated system, supporting performance across all Ninety9 Degrees classes while keeping the body operating efficiently at 99°.
