@nycdad,
If possible get out and walk more. If not get yourself some exercise equipment.
A vertical climber is a pretty good one, but there's loads of different equipment on the market, expensive and non-expensive.
Find one you feel you could and would use.
Control what food you buy, don't buy **** and definitely no take-aways.
Loads of fruit and veggies.
If you need a gee up to get you motivated try using some CBD oil.
That can put a spring in your step.
I'm 58. I've already had a heart attack and weight had a lot to do with it.
So don't delay. Start now.
