One Arm Dumbbell Tricep Extension Instructions

  • Stand up straight with a dumbbell in one hand with your feet about shoulder width apart. Position the dumbbell above your head with the arm fully extended to be in starting position.
  • Lower the dumbbell in a semicircular motion behind your head until your forearm is ideally touching your bicep. Remember to keep your upper arm close to your head and your elbow in.
  • Bring the dumbbell back up to starting position via tricep muscle.
  • Repeat for desired reps and switch to other arm.
