When to use it
Use when wanting to train grip and biceps together.
Who it's for
Intermediate lifters wanting grip strength and arm size.
Use significantly lighter weight than normal curls—your grip will fail before your biceps do with a thick handle. Secure fat grip attachments tightly so they do not spin. Focus on squeezing the handle as hard as possible throughout.
