Strategies To Lose Weight Fast

I’ve got a pretty decent body in general, although I would feel much more confident if I had slimmer legs. Would biking help me to achieve that?

I want to have slimmer legs, I no diet alone or exercise alone wont work, but was just wondering what exercises are best for this? In particular my inner thighs. Anyone know of any good exercise gadgets too for this? I want toning exercises I can do at home.
