I would like to add that if you really hate lunges and sqauts, try doing them on a fitness ball. Squats are still hard work, but if you support your back on the ball you won't strain as much, plus, hit the muscle group intended (as in avoiding hurting the lower back).

You can also do a lunges on the ball by sitting side ways, hand on a wall and lunging up and down so your bottom hits the ball as you lower. They are much harder than you think.

I like doing these 2 muscle groups in this fashion because they do not put a lot of pressure on the knees/give good back support...but, they are still hard!
