Stop! You’re doing it wrong.
If you want happy shoulders while developing your chest, shoulder and tricep muscles, avoid straight arms for chest flies and wide arms/hands for push ups.
Instead, protect your shoulders by balancing the weight of the DB over the elbow for chest flies and keeping the hands and elbows close to your sides for push ups.
And don’t be afraid to pick up some weight!
Once you have the form correct, a good rep range is between 8-12 for strength and muscle building.
If you can’t get 8 reps, it may be too heavy to do with proper form.
If you can get more than 12 reps, you can probably increase the weight safely.
