Thats not really new ... maybe you should try out this neat little invention called audiobooks ...
3 years ago when i was 32 i was one of those typical early 30th office junkies to fat to weak.
One morning after christmas time woke up at 5 a.m. i drove to town, i bought myself
1 iPod Nano
1 subsciption to audible
1 threadmill
1 Polar pulse watch
In 4 month i went from 92kg to 70kg (in the meantime i was nearly eating the same stuff then before) then began to build up weight in gym to 75kg and now i run marathons, run at least 1 hour in the morning every day excapt sundays, 3 times a week doing ninjitsu and krav maga ...
Yeah it all began with audiobooks but to do it right it will need one much much much more important thing ... your will to change ^^
