Hi Bugsbunny - I would definately get a mat especially for the core workouts as you spend most of the time on the floor. Keeps the sweat off the carpet
and gives you just a bit of cushioning to the back - vital for the oldies amongst us!
I've only been on the bells for two weeks. First week was spent practising moves Kron had kindly posted whilst I was waiting for my Kettleworx DVDs to arrive. Last week was my first week proper and I'm about to do Wk2 Cardio in about 30mins once breakfast has gone down. I am sticking to set days of Sunday,Tuesday and Thursday as these fit in with my work.
I really would recommend Kettleworx. I have a lot of weight to lose and would never go to a gym or the pool due to embarrasment. Also I have mahoosive knockers so the thought of jumping about would not be good. Too uncomfortable and don't fancy a couple of black eyes!
Hopefully KB will be good for you because of your time constraints.
Finally and most importantly, that is one of my cats in the photo. His name is Hartson and he is a big ginger softie of a lump. I also have his mum, Florence who is tiny by comparison but very feisty! Hartson spends most of his days on the kitchen table stretched out in patches of sunlight and then turns into a shrew killing machine at night!
