The Tumbl Trak Booster Block is a 48" x 18" x 8" foam training block built for gymnastics clubs, school PE programmes, martial arts studios, and home training spaces across North America. Covered in 18 oz. knife-coated vinyl over a firm polyurethane foam core and rated to 200 lbs, it is the kind of equipment that earns a permanent spot on the gymnasium floor because it never stops being useful. Coaches who own one block find uses for it in almost every session. Coaches who own several unlock a different level of versatility entirely.
The Velcro system is what makes it genuinely different from a standard foam block. Loop Velcro runs along the top four edges and hook Velcro runs along the sides and bottom, allowing blocks to connect side-by-side, end-to-end, or stacked on top of one another without tools or clamps. A single block gives you an 8-inch elevated platform. Two blocks stacked give you 16 inches. Three give you 24. The same logic applies horizontally: link them end-to-end for a longer run-up surface, or side-by-side for a wider landing zone.
How Coaches & Programmes Use the Tumbl Trak Booster Block
- Spotting station for beam, bar, and vaulting - position one or more blocks to create a raised surface at the exact height needed for the coach to assist safely during skill progressions on beam, uneven bars, and vault
- Height adjustment for the Orbiter - two Booster Blocks placed beneath the Orbiter allow athletes shorter than approximately 5 feet to access back handspring, front handspring, and round-off progressions that would otherwise be out of reach
- Plyometric and warm-up station - a stable platform for box jumps, step-ups, depth drops, and plyometric conditioning circuits; the 18 oz. vinyl surface holds position on carpet foam surfaces via the hook Velcro base
- Adjustable spotting block for tumbling - place blocks at the start of a tumbling pass to create a raised launch surface that adjusts the angle and difficulty of approach drills without permanent floor modifications
- Creative height customisation - mix and match single blocks in any combination to achieve the precise platform height needed for any drill, progression, or athlete size
Key Features of the Tumbl Trak Booster Block
-
48" x 18" x 8" Dimensions - The block's 4-foot length provides a substantial training surface for standing, jumping, and landing activities, while the 8-inch height creates a meaningful elevation step that translates directly to real spotting and skill-height scenarios in gymnastics and cheer training
-
18 oz. Knife-Coated Vinyl Covering - The same 18 oz. knife-coated vinyl used across Tumbl Trak's professional mat range; knife-coating bonds the vinyl directly to a reinforced woven base fabric for superior tearing strength, peeling resistance, and long-term durability under repeated daily use; wipe clean with a damp cloth and mild soapy solution
-
Firm Polyurethane Foam Core - 40 KG/m3 Density - The foam core is constructed to 40 KG/m3 (approximately 2.5 lbs/ft3) density, giving the block the rigidity needed for stable standing, landing, and spotting without the surface softness that would compromise balance and approach drills; rated to 200 lbs per block
-
Four-Direction Velcro Connection System - Loop Velcro runs along the top four edges and hook Velcro along the sides and bottom, allowing blocks to connect securely side-by-side, end-to-end, or stacked on top of one another; the connection system is stable enough for multi-block stacking under a 200 lb load per block
-
Loop Velcro Top Edges for Stacking - The loop Velcro on the top edges bonds to the hook Velcro on the underside of the next block in the stack, creating a stable, non-slip connection at every level; blocks can be unstacked and reconfigured in seconds without tools
-
Hook Velcro Sides and Bottom for Floor Stability - The hook Velcro on the bottom surface secures the block to carpet bonded foam and loop Velcro floor surfaces, preventing the block from shifting under load during active landing and training activities
-
Available in Four Colours - Red, Black, Purple, and Royal Blue; colour selection allows gyms to designate specific blocks for specific stations or height configurations by colour, simplifying session setup and teardown
-
CPSIA-Compliant Materials - All materials meet CPSIA safety standards, confirming suitability for children and satisfying the purchasing requirements of school and institutional gym programmes
-
Designed in the USA - Designed by Tumbl Trak in the USA to commercial gymnasium standards
Skills and Development Benefits
-
Strength & Explosive Power - Box jumps, step-ups, depth drops, and plyometric drills performed on and off the Booster Block develop lower-body strength and explosive power across a wide range of training levels from preschool recreational classes through competitive athletic programmes
-
Motor Planning & Spatial Awareness - Climbing onto, jumping from, and navigating around single and multi-block configurations engages the motor planning system in a progressively challenging way, building the spatial awareness and movement sequencing skills that underpin safe, coordinated athletic performance
-
Balance & Postural Control - Standing, balancing, and initiating skills from an elevated surface challenges postural control and proprioceptive awareness in a safe, graduated format appropriate for beginners through advanced athletes
Note: Always use under supervision. A suitable landing mat or crash mat is strongly recommended adjacent to the block. Block is not waterproof. Clean with mild soapy solution only - do not use bleach-based cleaners.
Ideal for
- Gymnastics clubs and cheer programmes building flexible, multi-height spotting and skill stations
- Martial arts studios and dance programmes incorporating elevated training surfaces
- School physical education departments building plyometric and obstacle circuits
- Home training spaces for recreational gymnastics and fitness work
- Occupational therapy clinics incorporating elevated proprioceptive and balance challenges
- Any training space where height-adjustable, connectable foam platform equipment is needed
