I only have a Treadmill + an Exercise Ball at home..so for the rest of it..I improvise
For weights I use the biggest soup cans I have in the pantry, I use the side of my Treadmill as a step to do "step - ups", I run rather than walk up the stairs outside everytime I put a dirty nappy in the bin LOL..and this can be a few times a day..especially when I have visitors
Do some dancing around the house as this burns up some cal's, and the Kidlet's love it... get in and do some hard arse housework for your Mum...she'll love you for it and it's a fantastic workout
So as you see, there are sooooooo many things you can do or use around the home to get you into shape...if that's what you really want to do
Good luck..and try and aim for this being a long term weight loss experience..not just short term as it's just gonna come back and bite you on the bum if you don't keep at it afterwards.
