Exercise Instructions

  1. Set up for the two arm dumbbell extension by sitting on a 90 degree bench holding a dumbbell above your head using both hands.
  2. Be sure that the dumbbell is secure by holding it with both palms facing upward. 
  3. Keep your feet flat on the floor and your back straight. This is the starting position.
  4. Keeping your head up and eyes facing forward, slowly lower the dumbbell behind your head as far as possible, moving only at your elbow joints.
  5. Pause, and then slowly extend your arms back to the starting position, squeezing the triceps.
  6. Repeat for desired reps.

Exercise Tips:

  1. Keep the rep timing slow and controlled.
  2. Don't "rest" at the top of the movement by locking your elbows out.
  3. Focus on keeping your body as still as possible, moving only your forearms.
  4. Don't let your elbows flare out as you move the dumbbell.

Should I alternate which hand is closest to the top of the dumbbell each set? Or do both triceps get equal workouts, regardless of hand position?

I'm no expert, but I usually place my offhand first.

E.g. I am right handed, so my left goes first.

I reckon my weaker arm can always do with some extra effort!

If the pain feels like a 'twinge' or nervy, I wouldn't panic, during the tricep extension it is the top of the tricep nearest the elbow that is tightening, just lower the weight to not over do it.

good luck

Does it matter at all which thumb is overlapping the other I always switch my thumbs half way through sets, does it matter at all is what I'm asking

Indeed, Morningstar (above) addressed this pretty well... Hydration and patience (lowering your weight until your joints catch up) should help. Gotta be patient and listen to your body. If something is cracking, slow down...or take a break. Make sure you have your recovery time...

Whats wrong if Im feeling pain at my elbows joints (the nerves)?
Should I warm up better or am I doing something wrong with the exercise?

Hydrate before exercising, I used to have the same problem until I started tracking my water intake. Also, being warmed up and stretched before an exercise like this is a must. And if it's still wearing down on your joints, go 5 pounds lower than what you're doing now. Just my opinions. Not a medical or fitness expert.

I used some heat lotion and wrapped my elbows for a couple of nights. On the next workout I lowered a bit the weight and now I feel it comfy. I'll keep an eye on the hydration thing also. Thx for the advice.

argy,this motion is a great tricep movement.But it will put alot of stress on the elbow joint.I would recommend a less weight.And not doing as many. This is my favorite tricep exercise but will hurt if over done.I get the pain from going to heavy.
