I am 45 and sucked into gym memberships for most of my life. Took me a (fake) doctor report to get out of the membership agreement.
I put on weight immediately and became 105Kg, post office was recommending me to get my own post code :-D
I discovered the free gym opportunities around through a website called livelifegetactive.com.au and following those now.
I am sitting on my bum all day in front of a computer so 2000 cal a day is a myth for me. Eating only once a day (dinner) is enough for me plus 3 days a week heavy exercise mostly using our own body weight within the group fitness classes I join.
I am 95Kg now and planning to loose more.
I also do professional stretching in a group class
and let me tell you, that was I what I was missing my whole life. Even my walking changes after a 45m stretching session.
After working in the garden for a day, I am completely wasted and can not even lift a finger in the evening. I do what I've learned from stretching classes for about 25 minutes, concentrating on aching muscles and a new me comes out of it.
