These are the first three tricep movements I ever did and they still are some of the best. Save for later, Cause it’s fat arm Friday!
A effective tricep workout should hit the long, medial and lateral heads. And although you can’t selectively isolate each head of the Tricep, there are different exercises you should make sure you do. For example any movement that is overhead will always stretch and work the long head.
Today’s tricep workout.

1️⃣. Cable tricep extensions
3x 20.

2️⃣. Dips
15, 12, 10 go heavier on each set. Reach failure

3️⃣. Skull crushers
3x8
