1. Bicep Curl with Alternating Lunge
    We like multi-tasking, especially during the holidays. The lunge with bicep curl is all about juggling multiple muscle groups at once. You will lengthen and tone your arms and also firm up your lower body. Stand with your knows slightly bent and a weight in each hand. Step forward with one leg and lower down to a lunge position. As you lunge, do a bicep curl with the opposite arm and raise the weight toward your chest. Then alternate to the other side and repeat 12-15 times.
