i found that for healthy lifestyle simple daily routine and some rules may significantly increase the level of muscle and joint functionality.
this is what i found valuable for me:
i start my day by 10 minutes of meditation. straight back, deep breath. (during the day i also practice proper posture);
i use only comfortable shoes for walking and running;
i try not to carry heavy things (above 10lb);
i wear snogg belt during working hours for blood stimulation;
yoga - love every exercise;
i listen for smooth jazz in the morning and quiet relaxation music before sleep. that gets and keeps my mind in check.
that’s what work for me, and i hope will work fine for you too.
please share if you have something valuable and effective.
