Gardening is quite a nice way of exercising. Most of the work is manual and you work at your own pace. My garden is located near a stream where I have farmed various horticultural crops in the past though currently its fallow. I use rudimentary tools like hoes to till the land and jerrycans to water the plants. This yields a positive dividend in terms of exercise. It gets better when the weather is cold because I can do alot of work.
