From my personal experience you can grow from using machines , but you should also be using free weights as well.

Stay tuned I will be uploading my daily eating videos soon.

Crazy arm pumps from leg day is crazy

4 sets 12-15 reps each side

Add this to your bicep routine, cable spider curls four sets 10 - 12 reps

Here is my current physique after training for 10 years naturally without using any steroids.

Cable Lateral Flys
Five sets 12 to 15 reps each side use a lightweight

This should be the first bicep exercise you do on bicep day

Ever since I started doing one arm at a time, my biceps have been substantially growing.

Spider curls have really helped me develop my arms, especially my forearms, it's given them that blocky look

Now there's two different variations you can do for this exercise. You could do them standing, which I prefer, or you could do them sitting down on a bench, just do whichever one feels best for you.

The arm blaster is meant to keep your arms, locked in one position to really isolate your biceps. This process requires you to not be able to cheat at all really working for each rep.
