I do some moderate exercise (40 min light walking 4 times a week, 1-2 weight sessions at home) a week. Late 40s and on HRT.
I have 2 month's gardening leave and want to get as fit as possible.
I'm going to join a gym and have plenty of time every week.
What should I do to get as fit as possible (muscle and stamina) so I have a good foundation for when I go back to work?
