"as we age, weights and boulders are our friends..."
this is so true. my comments about it is about how.
For me it has been important to:
Let go of magical thinking. : results are because of personal effort. There is no magic that makes a flabby belly be slim.
Realise that it takes (a lot of) time. Put away the weighing scales and don't stare in the mirror.
Educate myself. Read books about weightlifting, resistance training, aerobics and stretching. All of those not just one. (muscles weigh more + muscles at rest burn fat etc...)
Going slow. It's going to take time. Learning to be patient is going to be essential to success. Let go of the idea of losing fat weight quickly.
