Pace it up

Tone your Thighs, take long, brisk walks

Your pace should be faster than normal but not as fast as running. You want to get your heart pumping a little faster than normal but you do not want to put too much stress on your heart. You should walk for about 45 minutes to an hour a day, and if you can find a few gentle hills, your walk will be additionally slimming. Going up and down hills is a great way to tone your legs.
