Worked up to it over time.
6 days per week:
Alternate squats one day (with upper body push day) and deadlifts the next (with upper body pull day). Calves every day and sometimes other stuff thrown in if I feel good.
One day per week: kettle bell swings, jump rope, and/or a long hike
I read an article a f ew years ago that challenged the myth that legs need to heal from workouts and suggested that daily leg workouts are good for the rest of the body, hormones, etc.
People are supposed to be on their feet every day.
