## Overview

The Surge BOSU 40 is a water-filled, adjustable weight training tool designed to create dynamic instability through shifting water. With a weight range of 8 to 40 lbs and three grip options, it targets core stabilizers and joints for functional strength training. Made in the USA and supported by downloadable workouts, it’s perfect for professionals seeking versatile, engaging fitness challenges.

## Description

The SURGE® is a cutting-edge hydro-training device that uses water to provide an unstable load. Strategically placed angles allow the water to crash and shift, forcing your muscles to react to constantly shifting water, creating top-down instability. The Surge® provides a unique challenge to the joints and stabilizing muscles by forcing the body to resist and control the unpredictable nature of the shifting water. Three different grip options give the Surge® the versatility demanded in today’s training. From farmer’s carries to overhead lunges, the Surge® will help you achieve and exceed your fitness goals by training your body to react to real life movements. The Surge® 40 ranges from 8-40 lbs and the Surge® 60 ranges from 10-60 lbs when filled with water.

Review: So. Much. Fun! - Just added between 15 & 20 lbs of water for my current set of clients. Today was our first day and we did everything from chin rows (holding it vertically by one black handle) to sumo squats, to curtsies, to bicep curls (black handles-awesome!!). We had a lot of fun just messing around and seeing what we could come up with. This thing has so much potential! Someone said you can’t see the water in the clear one...you can but clearly they dyed the water in the BOSU video so it doesn’t show up like that. You can easily see the water level, though. The screws were cranky about going in for the handle installation, so be ready to boss them around. A few threatening words and hard cranks with a Phillips should do it. Great piece of equipment!
Review: Not cheap, cheap plastic - Nothing beats a good old fashioned gym with weights. Not worth the 100 some dollars it costs when it looks like it cost 2 bucks to make. Virtually impossible to get the water out once you put it in because of its design. Plug can pop out with heavy use.
