Dumbbell Alternating Front Raise- Standing with feet hip with apart, hold two dumbbells in front of your upper legs, with elbows slightly bent. Raise one dumbbell upwards and forwards, until it is just past shoulder height. Slowly lower and return to the starting position, and repeat with your opposite arm. Alternate arms, completing desired repetitions. 
TRAINING TIP: Make sure you are not swinging your arms and using momentum to complete the reps. Really focus on contracting your delt, and using it to help raise your arm during the reps.
