The training your biceps every single day part. The biceps are a very small muscle group. Training them every day is counter productive. Hit each muscle group one a week, HARD, then let it rest.

bicep everyday = bicep pain

see the equation yet?

p.s. a muscle part should be left to rest at least 48 hours to get optimum benefits. go figure

i hope your arms doesn't look like this

not photochopped, it's just a common picture of a curlbro who doesn't work his shoulder but yes DOMS, at least rest for 48 hours for best recovery
