WHERE YOUR CORE IS FORGED

The Burn Vault is Underworld Fitness’s most brutal training chamber — a dedicated space where core strength meets functional power. From sculpted abs to explosive CrossFit circuits, this is where raw potential is hammered into real results.

Inside the Chamber

Equipment Roster

Specialized abs and CrossFit equipment engineered to forge explosive strength, agility, and an unbreakable core.

Power Racks & Squat Stations

Heavy-duty power racks with safety catches, multiple J-hook positions, and dedicated squat platforms for maximum safety and performance.

Cable Crossover System

Full-stack dual-cable machine with adjustable pulleys for every angle of chest, back, shoulder, and arm training.

Leg Press & Hack Squat

Heavy-duty plate-loaded leg press and hack squat machines to build quads, hamstrings, and glutes with precision.

Smith Machine

Guided barbell path for controlled pressing, squatting, and rowing movements — ideal for both heavy lifting and technique work.

Chest Press Stations

Flat, incline, and decline chest press machines engineered to isolate every fibre of the pectoral muscles for complete development.

Lat Pulldown & Seated Row

Wide-grip, close-grip, and neutral-grip attachments for a full range of back width and thickness movements.

Shoulder Press Machines

Plate-loaded and selectorised shoulder press machines for developing balanced deltoid strength and mass.

Olympic Barbells & Plates

Full set of Olympic barbells, EZ-bars, and calibrated plates ranging from 1.25 kg to 25 kg discs for precise loading.

The Philosophy

"The core is the throne of all strength. Build it here, in the vault, and nothing can break you."
