I lost all of my weight with no exercise, from my experience it is not necessary. Phases of doing a lot of walking did seem to speed things up. But too much exercise can make you hungry and overeat, or drink sugary energy drinks. There is such a regime as carb-loading, but it has to be done just right.
The way to a six-pack is mainly to burn off the fat covering those muscles. But a couple of exercises are also rumoured to be especially good, according to Tim Ferriss, one of the heroes of this Astral Projects blog:-
For abs, as I keep losing eBay auctions for Bosu balance balls, although a semi-inflated gym ball can substitute, I am going with my WonderCore, sit ups and arm exercises whilst watching Netflix.
Weights- good for upping the testosterone, perhaps not ideal for the ladies so much in that respect. Myself and punk son have a bench in the Crematorium Penthouse. Step two- to use it, apart from to dry clothes on.
Again there are some optimal moves, if you use the right “form”:-
I have now been to the gym a grand total of one time. I was briefly trapped under a barbell. I didn’t know the bar itself weighed 20kg!
I have also attended two HIIT classes, run by a tiny Spanish tyrant, I am in a lengthy hiatus after the only other man in the group was hospitalised last time. Awkward.
I am not sure about cardio for guys. Exercise bikes have an alarming numbing effect on a certain area I feel can’t be good. My home treadmill smoked for a week, before actually catching fire and being taken away by Russians for scrap. It seemed such a bargain on eBay too.
It appears walking for 20 minutes a day may be the sweet spot?
