If you walk for 30 minutes every day, that's a nice amount of exercise!!
Sometimes I can feel and hear a little cracking in my knees when I come up from a squat, I think that's maybe due to lack of exercise because there is no pain, so I think I'm ok and haven't injured my self. The first few days was very tiring, now I'm getting used to it.
Thanks for your entry, and good luck!
Yes, life is good if you walk a little daily. Before taking up the habit, I suffered from night cramps. They are quite scary!
But now life smiles, I'm glad that it is like that for you too. Greetings, thanks for the good vibes and good luck!
