Keep in mind that as you curl the dumbbells, your forearms must rotate to face your shoulder. Upon returning to the starting position, you must reverse the motion so that your palms are facing each other again.
Keep a neutral back and upright torso throughout the exercise.
The dumbbell squat to dumbbell curl combines two exercises and is good for functional fitness. The dumbbell squat is a compound exercise that emphasizes your leg and elbow flexor muscles. This is helpful for activities that use both leg and elbow flexor muscles at the same time, such as lifting a box off the floor. The dumbbell curl, on the other hand, specifically builds on your biceps.
