Monster Blocks
interlocking Olympic lifting blocks


The Worlds Only Interlocking,
Interchangeable, and Stackable Lifting Blocks

MonsterBlocks has unlimited uses and values in all types of weight training settings. They are primarily designed to be used as jerk blocks. Because of the modular adjustable heights, the can be used as low pull blocks from a height of 7.5 inches. MonsterBlocks allow the athlete to pull from varied heights in 5 inch increments during training to build avenues of explosive strength. These boxes can serve several other duties as well. They can be used as modular plyometric jumping boxes, and can also be set up to spot a weight lifter to prevent injury.

PERFECT FOR-
Jerk Blocks, Low Blocks for Snatch & Cleans,
or Tall Plyo Blocks


Interlocking Blocks

With this unique interlocking design, each section is fully supported with 7 ribs for unparalleled strength and stability. However, each block portion only weighs 15 to 30 pounds, making adjustments quick and easy.

Adjustable Heights

MonsterBlocks are designed to be used from as low as 7.5 inches to as high as you need. (5 inches to 35+ inches) MonsterBlocks allow the athlete unparalleled adjustable heights. This degree of adjustability will allow athlete to train each skill more precisely.

4 Layered Lids

We use High Density Polymer Plastic HDPP between the two bottom layers of the lid, it keeps the wood from compressing or mis-shaping. The addition of the 3/4 inch thick, water-jet custom cut Vulcanized rubber on top, the 4 layer lids are over-engineered to handle the constant abuse of training.

Each Section is Built Smarter

All MonsterBlocks are made with cabinet grade, high end, 3/4 plywood. Our plywood is specially purchased and inspected to be free of voids and have clean lines. Sparing nothing, they are assembled with 1.5 inch, full thread, self drilling screws to ensure no splits and a secure finish that will last years of hard abuse

Customizable w/ Logo or Design

The art will last for years to come as it is inked directly into the wood and not just painted onto the surface. We can add your personal FULL COLOR custom logo to your MonsterBlocks with just about any color. We will place it directly onto the front side of the Monsterblocks. All we need is your art work and we can do it…

MonsterBlock Testimonial

MonsterBlocks are awesome! We just received ours last week, got them together and have started putting them to good use. Upon receiving the jerk boxes the first thing we noticed was how simple they are to assemble, immediately after assembly we could feel how solid they were and they proved it the first time we used them for some split jerks…ROCK SOLID! In addition Sam’s customer service and attentiveness to his costumers is second to none, he was in close contact throughout the entire order, production and delivery process and followed up with us immediately to see what our thoughts were. If you aren’t buying your jerk boxes from BuyMonsterBox you are wrong!

More Reasons to be Confident

Premium Grade Wood

We believes in only using the finest materials available in our line! All MonsterBlocks are made with cabinet grade, high end, 3/4 plywood. Our plywood is specially purchased and inspected to be free of voids and have clean lines. The MonsterBlocks are assembled (Local delivery) or shipped with 2 inch, fully threaded, self drilling screws to ensure no splits and a secure finish that will last years of hard abuse. Even though it is much more expensive to use screws, you will never see nails or trim tacks used as they will fail eventually.

Built with Polymer Plastic

The secret sauce in our MonsterBlocks is the 1/2 inch of High Density Polymer Plastic HDPP between the two bottom layers of the lid. I custom order the Polymer Plastic out of California. By using the Polymer Plastic between the two sheets of plywood, it keeps the wood from compressing, mis-shaping, and eventually failing. Its like the rebar in concrete. With the addition of the 3/4 inch thick, water-jet custom cut Vulcanized rubber on top, the 4 layer lids / crash pads are over-engineered to handle the constant abuse a busy facility can dish out.
