exercise bike and weights are perfect, you actually dont need to buy anything else to be honest. I lost over 5 stone with cal counting and I also did bits on the exercise every night, it really helped, and I loved it, I think 30 mins on the exercise bike is the equivalent of a treadmill, basically bike is better than walking, you can change the settings. If your going only for weight loss, go fast with no resistance, if you want to build muscle put on loads of resistance and not as much speed. I used to do 30 mins on the bike, (with about 3 mins break in the middle) about 15mins with the weights and approx 40 crunches/sit ups. This was a few years ago but now im in kinda the same situation as yourself, I work all day, OH watches kids then when I get home he works & I watch kids, so no time for gym, plus cant afford it anyway! I gave my bike away when i was pregnant but iv been given an uphill treadmill, which I want to start using again. I need exercise in my life and the only way I can do it is at home, by myself, i'll be interested to see the responses on this. I was thinking of doing a bit of googling and coming up with some sort of plan for myself!?! Good luck xxx
