In this quick video, Adam Sjogren, Certified Personal Trainer at Flex Level Fitness demonstrates the Toast Curl. A Toast Curl is a variation of standard hammer curls that emphasizes the upper forearm and outer bicep, or brachialis. In only 8 weeks, adding this exercise to the weekly arm regimen of Flex Level Fitness clients and focusing on PROPER FORM, we have achieved total transformations of the arm, and in some cases, even turned a lagging body part into a strength!
