I've just got 1 x 20kg kettlebell so I do a lot of high rep workouts with it when I can't get to the gym..
I go to a gym in the city centre which is easier for me to go to before/during/after work... But it's too far to just nip to the gym if I'm not at work, so kettlebells are a perfect workout aid for me at home
Some routines are knackering as well! Good for strength and cardio I imagine!!
I downloaded kb fat loss & kb muscle apps on my Iphone...there cheap and give a brief idea of technique and a few workouts/exercises
