It is worth noting that throughout the next 4 weeks, these are my preferences - not necessarily the generic fitness preferences.
#1 - Skull crush/overhead extension
Still my favorite tricep exercise, this exercise but dedicated attention on the long head of the tricep.
#2 - Overhand/reverse bicep curl
My favorite bicep exercise as it helps build the front of the forearm as you develop the bicep.
#3 - Tricep pushdown
The pushdown can be done with multiple attachments but the rope is often the most popular.
#4 - Rotating bicep curl
Rotating the arm throughout the movement allows you to work the bicep fully and replicate external rotation through the elbow
#5 - Chin Up & Dip
Not necessarily an arm exercises, you can't ignore the benefit these two exercises have on arm development.
Be your best!
