I hope you're a fan of supersets, because today's workout has four on the docket!! Remember to keep your rest between 90 seconds and two minutes, depending on the exercise. Don't rush the exercises, and keep a steady cadence.
Also, pay close attention to the exact exercise. For example, for 1-1/4 dumbbell seated incline curls, bring the weight all the way up, lower it about a quarter of the way, bring it back to shoulder level, and then lower it completely for one complete rep.
The additional quarter rep will increase the time the muscle is under tension, which means more mass-building stress on your biceps!
