My neighbor is in constant motion. She stands just over 5 feet, but that small frame delivers purpose and determination...in addition to speed. When it comes lawn and garden work, no one can keep up with her. Trimming. Weeding. Planting. Harvesting. Mowing. She even mows for another neighbor. She rarely stops moving. And she's got 10 years on me. She's the epitome of "YES, you can count yard work as exercise!" It depends on what you're doing, but aerobic conditioning, strength training, and flexibility, can all be done outside. But, take care.
Don't go crazy as the weather turns nicer. If you've been more sloth-like all winter long, don't expect to zip right out there and mow lawn, weed the gardens and plant all in one day. That's a recipe for bit time pain and suffering. Be sure to warm up by walking and going through some general full body motions to get prepped for your yard time.
And, be mindful. When your body gets tired, listen and respect what it's saying. Fatigue means it's time to stop for the day, stretch out, and do the rest tomorrow. It doesn't mean to man-up and bust your body trying to get it all done. Respect yourself.
It's a beautiful time of year. Time to enjoy your body in motion and learn to use mindfulness to understand it's limits. You'll get along much better inside that body of yours if you do...
