If you’ve seen the P90X® infomercial, gotten excited, and then asked yourself How does P90X work?, then this 12-part series is for you. Part 3 covers the P90X Shoulder and Arm workout.

Finally – a P90X workout that didn’t leave me wanting to curl up into the fetal position and cry for Momma! That being said, the P90X Shoulder and Arm routine is no joke, and is every bit as effective as every other P90X workout that I have been through.

Would you believe that real weight loss and noticeable muscle gain can happen without ever setting foot inside a gym? YES is the answer, and here is how I did it!

The Dumbbell Supination Curl is one of the best overall bicep exercises because it works the bicep muscles from several different angles and it engages the forearm muscles as well.

The Bicep Concentration Curl is an effective bicep exercise because it will isolate the bicep muscle, while at the same time giving a point of leverage so that you can move more weight, resulting in faster progress.
