You should go to a gym and work with a trusted spotter if you’re new to this process. This one is yet another great exercise that can help strengthen your pectoral muscles and everything you have to do is find some dumbbells that are heavy enough to have an impact but not so heavy that they cause strain, somewhere around 7-12 pounds, and then  raise them in the air. You might as well  just do this exercise at home without a workout bench. Here we have how to do it:
- First hold the dumbbells in both your hands with your hands resting on your thighs while your palms should be facing downward.
- Lift these up in the air while also keeping your hands straight, with your arms slightly bent.
- Once the dumbbells are being raised above your head, in a gentle way  lower them to your sides and repeat.
- You might as well  think of this maneuver as mimicking the movements of a pushup while being on your back
