Brother that's awesome!!! I think I read earlier that you were starting from 100KG. Sorry if this is a repeat tale from me, but I got serious about my weight loss when I had a mass of 100.0 KG at the doctor's office. However, that was over 4 years ago. Well, now I am closer to 89, but that can swing fully 3KG ( ~7 lbs) in either direction from one day to the next. BTW I wanted to get down to about your target weight when I started. However, I have plateaued where I am now, and I'm not too worried about it. I think I look a little overweight now, but definitely not carrying an abdomen that made it impossible to see my feet without bending most of the way forward! Also, the type of potential mates that I pursue generally like guys with a degree of "padding," so I don't think my extra weight is getting me rejected when I wouldn't otherwise, lol!
The second thing I reacted to when I read the above is about over-training. I can tell you from my experience, that if I think I am barely pushing myself, I am breaking down my muscle tissue through workouts faster than I can recover before the next workout, which means more harm than strength. So by the time I feel like I'm overdoing it, I've already pulled a few connective tissues out of position. Overtraining injuries are easy to get and totally suck.
Well, I totally fail at prioritizing exercise and reading because I get lost in internet rabbit holes - meaning all I read is basically wikipedia and IMDB. Nonetheless, during the times when I am not hating myself for being an unemployed loser - I find that exercise first thing in the morning works out best. I prefer the cooler weather and it's easier to not get it crowded out when I have it in my morning routine.
Hope that entertains! or if not, at least helps!
