Instructions for Proper Form
Machine Fly is a variation on the more standard Dumbbell Fly. This isolation chest exercise primarily targets the chest, but also recruits the shoulders. The use of a machine makes the exercise more stable allowing you to focus on exertion or learn the movement with minimal risk of injury. This is a great exercise for beginners looking to learn the movement, or advanced lifters looking to push this movement to it’s limit.
- Sit upright in a fly machine while squeezing your shoulder blades together and placing your heels firmly on the ground underneath your knees shoulder-width apart.
- The back pad should be contact with your head, shoulders, and butt at all times.
- Brace your core to keep your spine in a stationary neutral position.
- Grab ahold of the handles with your palms facing forward.
- Keeping your arms extended and elbows slightly bent, create a wide arc to flex the handles together.
- Return back to the starting position.
Common Form Mistakes
Overusing Machines
Machines are great pieces of equipment, however they do hinder your ability to develop smaller stabilizing muscles. Try to work in other variations that require you to stabilize the movement as well.
High Resistance
Extending your arms away from your body increases the tension placed on your joint’s and muscles. Keep the resistance for this exercise fairly light, and focus on moving slowly, and controlling the movement before you add more resistance.

Alternatives & Variations to Machine Fly
1. Cable Crossover Fly
97.3 mSCORESWAPPED 10,820 TIMESCable Crossover Fly is an isolation exercise that targets the chest. It’s a variation on the more standard Dumbbell Fly, and can easily be adapted to further isolate specific areas of the chest. Using cables to add resistance allows you to keep more consistent tension on your chest, as well as control the angle that the resistance is coming from.
2. Dumbbell Fly
98.3 mSCORESWAPPED 9,378 TIMESDumbbell Fly’s are one of the most common isolation chest exercises, and for good. It primarily targets the muscles in the chest, but also recruits the shoulders for stability. The use of dumbbells ensures that you’re targeting each side of the body independently, and prevents compensating for any weaknesses between sides. In addition the isolated nature of this exercise is a great way to fatigue your chest, and focus on building both muscle mass and increasing strength in your chest.
3. Machine Bench Press
93.5 mSCORESWAPPED 5,348 TIMESMachine Bench Press is a compound exercise the primarily targets the chest, shoulders, and triceps. The use of a machine forces you to use a fixed range of motion which can be a great way to learn the movement, or to focus your effort on exertion rather than stability.
4. Hammerstrength Chest Press
94.3 mSCORESWAPPED 2,706 TIMESHammerstrength Chest Press is a variation on the more standard Barbell Bench Press. Similar to Bench Press, this compound exercise primarily targets your chest, shoulders, and triceps. The use of a Hammerstrength machine forces you to use a fixed range of motion. This can help you either learn the movement, or focus your efforts on exertion rather than stability.
5. Dumbbell Bench Press
99.7 mSCORESWAPPED 2,542 TIMESDumbbell Bench Press is a variation on the standard Bench Press. Like Bench Press, this compound exercise primarily targets the chest, while also training the triceps and shoulders. The use of dumbbells allows for greater instability which can help you become more stable on pushing movements in general, while also isolating each side of the body to prevent you from compensating for any weaknesses between sides.
6. Dumbbell Incline Fly
91.1 mSCORESWAPPED 1,874 TIMESDumbbell Incline Fly emphasizes the upper chest, improving muscle definition and shoulder flexibility. Performed on an incline, it targets the upper pectorals while also engaging deltoids and triceps, offering a comprehensive upper body workout that enhances strength and aesthetics.
7. Dumbbell Incline Bench Press
99 mSCORESWAPPED 1,752 TIMESDumbbell Incline Bench Press is a variation on the more standard Barbell Incline Bench Press. This compound exercise primarily targets the chest, but the incline also places more emphasis on the shoulders. The use of dumbbells makes this exercise more unstable than its barbell counterpart, while also forcing you to address any strength discrepancies between sides.
8. Barbell Bench Press
99.2 mSCORESWAPPED 1,722 TIMESBench Press is one of the three Powerlifting movements, and one of the most common upper body exercises. It’s a fantastic compound exercise that can help you build strength in your chest, shoulders, and triceps. It’s a staple in most fitness programs, and is often used as a metric for tracking upper body strength in general.
9. Low Cable Chest Fly
86.8 mSCORESWAPPED 1,656 TIMESLow Cable Chest Fly is an isolation exercise that primarily targets the chest. By using a low pulley setup, you emphasize the lower part of the chest more than other Fly variations. The cables provide consistent tension throughout the movement, and allow for greater control over the angle of resistance, enhancing muscle activation.

10. Push Up
94.5 mSCORESWAPPED 1,468 TIMESPush Ups may be the most recognizable exercises out there. It’s one of the best bodyweight exercises you can do, and is a great way to develop functional strength in your upper body for pushing movements. It’s fantastic for beginners, or anyone with limited equipment, while still being a great addition for even the most seasoned lifters.
