There are many different ways to improve your current exercise routine. What about doing the Bosu chest fly, what will the effects be?
The Bosu chest fly is a Bosu Ball exercise where you lie with your upper back on a Bosu Ball and move your slightly less than stretched arms from horizontal right above the ground to pointing up.
The main benefit of using a Bosu Ball instead of the floor is that your chest muscles can go through a larger range of motion. This is generally beneficial for muscle growth and strength progress.
Additionally, the Bosu Ball is more comfortable than the floor.
If you have a good weight bench available this is typically recommended over the Bosu Ball in terms of comfort, safety, and muscle growth.
Whether you should a Bosu chest fly or alternatives to your routine ultimately depends on things like your personal situation, personal preference, and training goals.
How to do a Bosu chest fly
As the name implies, to do the Bosu chest fly you need a good Bosu Ball. On top of that, you need some type of resistance like dumbbells, resistance bands, wrist weights, etc.
Once you have that, to do a Bosu chest fly with dumbbells take the following steps:
- Put the Bosu Ball with the flat side on the ground. Sit right in front of it.
- Lie down with your upper back on the top of the Bosu Ball with a dumbbell in each hand and against your chest. The position of your legs is not as relevant. For more stability you can put your feet flat on the ground.
- Push the dumbbells up vertically until your arms are slightly less than stretched and pointing up. Your hand palms should face each other and your hands should be as close together as possible.
- While keeping your arms slightly less than stretched slowly lower the dumbbells down sideways until your arms are right above the ground. Only your arms should move.
- Move your arms back to the position in step 3 in a controlled motion.
Keep your movements slow and controlled to make your muscles really work hard.
The main way to make the Bosu chest fly easier or harder is by adjusting the resistance you use. Do keep the Bosu Ball weight limits in mind if you do this.
A different type of modification is that you can change the angle of your upper body to focus on slightly different parts of your chest.
For example, the higher your shoulders are compared to your hips, the more you will focus on the upper part of your chest muscles (up to a certain point).
Bosu chest fly muscles worked
The Bosu chest fly is mainly a chest isolation exercise. You may need to engage your biceps a small amount to keep your arms less than stretched.
You can change what part of the chest muscles you focus on by changing the angle of your upper body. For example, by keeping your hips at a higher level than your chest you will work the lower part of your chest muscles more.
By doing the chest fly on a Bosu Ball instead of the ground, your chest muscles can go through a larger range of motion. This is generally beneficial for muscle growth and strength progress.
Keep in mind that a weight bench offers similar benefits in a safer, sturdier, and typically more comfortable way.
The way you build muscle in places like your chest is by engaging these muscles so that they get damaged enough.
This may sound counterintuitive but this damaging makes it so your body repairs these muscles, and adds a bit more to be better prepared to exert similar efforts in the future.
If you stick to exercises with the same weight, as your muscles become stronger this same effort may not damage your muscles enough to promote extra muscle growth.
By gradually increasing the resistance you use in the Bosu chest fly as you get stronger, you are better able to damage the muscles in a shorter amount of time.
If you don’t overdo it, give your body enough nutrients, and give your muscles enough rest this can in turn lead to faster and more chest muscle gain.
When you start adding extra weights to the exercise you do want to keep the Bosu Ball weight limits in mind. The standard at-home option from the Bosu brand has a 300 lbs weight capacity. Other models can vary.
