Prior to recent surgery the surgeon wanted me on a minimum 2 miles walking every day.
I gently sipped a redline during the morning and generally made the goal fairly easy.
I chugged the “extreme” (I looked it up) and started lifting. My pulse was around 180, and I take long breaks in between sets...
I don’t know your age, but walking daily is excellent for health, and peace of mind. Feel the Sun and wind, hear the birds etc.
