The BOSU Balance Trainer, AKA the BOSU Ball, was invented in 1999 by athlete and fitness product developer David Weck, as an alternative to a traditional stability ball.
An acronym that stands for “both sides up,” the BOSU ball resembles a rubber stability ball that has been cut in half then attached to a rigid plastic platform,
It can be used with either the flat or curved side resting on the floor, depending on the exercise you want to do.
BOSU ball workouts improve core strength, balance, flexibility, coordination, and cardiovascular fitness.  This versatility has led to it becoming a standard fitness tool in gyms across the world.
The concept behind this simple training tool is that exercising on an unstable surface engages small, as well as large muscles. This means workouts are comprehensive and extremely effective.
What Exercises Can I do with the BOSU Balance Trainer?
The BOSU Balance Trainer can be used to perform exercises such as Crunches, Planks, Presses, Squats, Bicep Curls, Lateral Shoulder Raises, Hip Extensions and more. It can also act as a step during cardio workouts.
Read on, to find out more about the BOSU Ball.
Why is the Bosu Balance Trainer so popular?
The BOSU Balance Trainer is popular with exercisers of every age and fitness level. This is largely due to its versatility, which enables the 
user to perform a vast range of toning and balancing exercises.
BOSU balls come with a workout guide and one or two total-body workout DVDs. The DVDs demonstrate cardio, toning, and stretching exercises, along with moves designed to improve balance and coordination. You can also create your own workouts.
Two balance balls can be utilized simultaneously, by resting your feet on one and your hands on the other. Used this way, you will further increase the benefits of exercises such as Planks and Push-Ups.
With a BOSU Ball, there is no adjustment phase as there can be when using a regular stability ball which tends to roll across the room until you get the hang of it.
Excellent for promoting good posture, I often use my BOSU Ball as a seat when watching TV.
Is the Bosu Ball more effective than a regular stability ball?Â
Two studies concluded that when used for strength training, BOSU Balls provide no extra benefits than traditional stability balls. Research has yet to be undertaken to determine if it delivers superior balance and coordination benefits. Studies also need to be done to see if it provides a better core workout than a regular stability ball.
Personally, I find the BOSU Balance Trainer enjoyable to use, and anything that keeps me interested in working out on those days I may not feel like it has got to be a good thing.
Again using Planks and Push-Ups as an example, when I do these with my feet resting on my BOSU Ball, the difficulty level is increased, and I feel that my muscles are getting a deeper and more effective workout.
Does the BOSU Balance Trainer come ready to use?
Before you can use your BOSU Balance Trainer, you will need to inflate it. A foot pump and instructions on how to use it will be in the box the ball comes in.
Be sure not to over-inflate the ball. If you do, it may leak air. While no big deal, rectifying it is a little fiddly. You will have to undo the screws that attach the ball to the base, realign the ball’s rim with the base, then tighten the screws and reinflate the ball with less air.
The BOSU Ball is available in four different versions. These include the BOSU Home Balance Trainer, the BOSU Pro Balance Trainer, the BOSU Sport Balance Trainer and, the newest addition to the range, the BOSU Elite Balance Trainer.  We will look at each of them below.
