Are you like many people these days and have a busy daily life? While wanting to improve your health, you don't seem to find the time. Well here's an easy 3 in 1 solution. Turn your lawn into a garden! Instead of driving across town and/or paying to work out, why not start a garden and get the exercise while doing something you enjoy. Also you can get tasty vegetables to add to home cooked meals.
Start small and use fallen leaves or grass clippings to amend the soil. Then pick up seeds from local hardware stores and begin your vegetable or flower garden. You will quickly feel the exercise even just moving around a bit more. The fresh air is great and the various activities are good for building core muscles and endurance. There are many resources online for stuff like this. Try searching Backyard Gardening or similar keywords.
After a few months of consistent work you can get nutritious vegetables, herbs etc... This will make your work easier as you get natural vitamins.
There you have it, an at home workout with a built-in nutrition plan. You can spend as much or as little time as you'd like.
