Yes, I still believe believe that gardening is excellent exercise with growing healthy food as a bonus!
However, I have just seen both sides of the coin. My mom loves her back door garden with amaryllis, daisies, fern, daisies, etc.
For 2 weeks I helped her recover from sciatica and spinal compression fracture, probably from osteoporesis. She didn't know what happened. Then we walked past garden, she said, "The last think I remember doing is watering these flowers!" So the light bulb went off that she probably strained her back from watering the plants since she fills small water containers from rain water pails and carries them to the plants. She thought she would be on pain meds the rest of her life.
Thankfully, with physical therapy she is making rapid recovery with less pain and more mobility.. I attribute her quick recovery to her daily gardening.
This was a good reminder to use good body mechanics to avoid back strain, use your strong legs, don't twist at the waist!
