Looking to build bigger arms? TFR PT James is here to tell you how...
“If you are struggling to grow your arms, I find it helps to have a dedicated Arm Day to increase weekly volume on the muscle group.
A lot of people will throw some triceps in after a chest day and some biceps in after a back day... this is still a good way to hit the arms, but it can lack the volume and intensity a dedicated arm day can provide to your training.
I always start with triceps; this ensures my elbows are warmed up prior to doing biceps. It also helps to get some blood moving into the muscle, and for me personally, I find triceps movements can be a bit heavier than biceps, so I like to do those whilst I have a higher energy level.
For triceps I do 2 cable movements to start, a heavier compound press down and a lighter unilateral movement. I find this warms my triceps up perfectly for the final heavier dumbbell movement; here’s my current three triceps exercises with sets and reps:
A: Straight Bar Cable Pushdown, Pronated Grip: 3 sets – 8-15 reps
B: Single Arm SG Cable Ext, Supinated Grip: 2 Sets - 10-15 Reps
C: DB Rolling Tricep Extension: 2 Sets - 6-10 Reps
Now my arms are warmer, I’ll move onto biceps...
Because I find my biceps fatigue quicker than my triceps, I like to start with the bigger bicep movement first; which allows me to utilise my remaining energy efficiently and get the most out of the exercise. I start with a superset of exercises to push as much blood as possible into the biceps. I also like to perform a drop-set for my final sets, lowering the weight and trying to match the reps, as my arms fatigue. Here are my current bicep exercises:
D1: BB Bicep Curls: 3 Sets – 10-15 Reps
D2: DB Reverse Curls: 3 Sets – 10-15 Reps
E1: Single Arm DB Preacher Curl: 2 Sets – 8-12 Reps
F1: DB Wrist Curls: 2 Sets – 12-20 Reps
Dedicated Arm Days don’t need to be complex or take a lifetime. Both triceps and biceps work with simple movements, so don’t overcomplicate them. Focus on the control and contraction, and give this a go next time you want to hit arms!
