You are doing great sir!
How many hours do you think the runs, circuits, and yoga amount to?
Paddle-boarding got me in pretty good shape last year and my back n core have lost a bit due to the not so fun cold water months - I can't think of an exercise like a good stroke of a paddle, and them rowers god some big shoulders!
Oh, and IF of course, if you're feeling middle class, aka skipping breakfast if yer too poor to eat three meals a day.
Exercise at 7:30 and skip breakfast? Not for me! Since I moved here though and evening meal is later it's possible to go to 10/11 am without anything solid. I start getting grumpy after that.
It must be at least 10 hours a week in total.
You gotta just blast past those hunger pains. If you can get through until 14.00 it becomes easier!
You'll be going for a while yet!
