Achieving a toned body requires two things. - Fat loss, and - Muscle gain
If you have a very high body fat percentage (>25%) it can take 12 weeks or more to start seeing noticeable changes in muscle definition.
The best way to get toned fast is with a combination of resistance training, dietary changes, and constant movement.
It is possible to get toned at home as long as you are following a consistent workout routine that uses the principle of progressive overload.
