I have read that exercise, especially vigorous exercise, does amazing things for prevention of breast cancer recurrences. Up to 40% risk reduction.

I did a lot of exercise today, but none of it was vigorous.

Personal training

arm bike (upper body cardio against resistance) for 10 mins

Rowing wiithout moving my legs - 20 mins

Arresting and foam rolling class, quite demanding - 69 mins

Some incidental walking captured by my Oura app

2 sets of Australian exercises and I might do the final third set right before bedtime
