What other Goddesses say,

“eeek where to begin! luv luv luv my classes! coming from more of a martial arts background I struggled so hard to find a class that really kept my interest and kept me motivated and I really felt like I had actually done something! for me it is all about feeling energised and toned, I had never been to a kettlebell class before this one and I started with the workshop which got me hooked, Lisa is a fab instructor and makes the classes so much fun and also interesting, I would usually attend Lean,and Warrior and Boom, which I really enjoy, but my fav is def Warrior, this class is so much fun I even get to box, and skip, also the ropes! so hard but so good! something I had not done for a long time, this class is hard but there are great rewards afterwards ,my arms have def toned up since starting these classes, I cannot recommend Lisa enough,if you want something that is different, fun, and will make you feel stronger and fitter, try any class but warrior rocks;-).”
