Hills
I am lucky where I live on the Kapiti coast there are some good hills to strengthen the legs. Nearby is the Barry Hadfield Nīkau Reserve. It is a shaded bush walk through large clusters of nikau palms along a gravel/muddy track. It leads up a steep but short staircase climb, only takes about 15 mins up but great to do before work.
