This has been a phenomenal way for me to be held accountable to not only have a GREAT workout, but also helps with focus and mental clarity. Since I started doing classes at Broadwing Martial Arts at the beginning of 2013, I have more energy, my body is more toned, and I have a great way to relieve stress, not to mention the fact that my confidence has dramatically increased!
