Personally I'd try two things to make the process easier: 1) Fit physical activity into your day to day life. I run to work but there are far less extreme ways to do this. Walk or cycle places, find a hobby that burns some calories etc. Leading a life that involves movement is far more sustainable than trying to start an exercise habit. 2) Try lots of different exercise routines. After a lot of trial and effort I've found running and swimming work best for me, with maybe 5/10 min weights after a swim. I've previously tried cycling, dumbbells, thai boxing and many many body weight/calisthenic/ natural movement type systems. Everyone's different so it's worth trying out a load of things to find which you'll actually enjoy.
