1. Prone Dumbbell Incline Curl

In the dumbbell prone incline curl, you perform a dumbbell curl with your chest against an incline bench, instead of your back. This keeps your arms in front of your body, which trains your biceps slightly differently than the incline dumbbell curl.
2. Incline Dumbbell Hammer Curl

The incline dumbbell hammer curl is similar to the regular incline dumbbell curl, only your palms face each other, not forward. This wrist orientation emphasizes the brachialis, a small muscle beneath the biceps that significantly adds to the biceps’ size and circumference.
3. Bayesian Curl

The main difference between the Bayesian cable curl and incline dumbbell curl is execution: in the Bayesian curl, you train each arm independently using a cable machine and while standing, whereas in the incline curl, you train both arms simultaneously using dumbbells and while seated.
However, both exercises work your biceps similarly and comparably, so you can use them interchangeably.
