If you have never attempted a circuit to hit your bicep then your missing out on a lot. A good powerful circuit can really induce massive gains on your bicep. So its time you stop missing out
So what is a circuit? Executing a group of exercises back to back with little or no rest is a circuit. Of course a group meaning more than 4 moves. Other wise your just doing a giant set. Originally circuits aren’t really used to build mass on your bicep. Actually they are made to itch out detail in you arm or targeted muscle. But if you know how to use the circuit you can utilize it in a manner to which it will help with muscle mass. And not just bicep size but shape
