Exercises to Tone Your Legs

This is such a simple topic but it constantly frustrates me when I see people (and Trainers) wasting their time on poor exercises. The fastest way to tone your legs is to use as much muscle as possible. This will obviously work more muscles in a shorter period of time but also burn more calories.
The biggest mistake I see is the use of Isolation exercises. These are great if you weigh 45-55kg and have <20% bodyfat but most people don't. Isolation exercises are the ones where only one joint moves. Yes, you've done them! You know, lying on the floor, on your side, and raising your leg. There are many of them and they are a waist of time for people looking to lose weight and tone their legs.
The best exercises are Compound. Compound exercises are those that use more than one muscle group. These are easy to pick out because you will have more than one joint moving. The best of these are Squats and Lunges. There are many forms of these so do a search, and tone those legs fast!
