44 years now, and started "body recomposition" a few months ago after my split up with my gf.
I was and still am at 71 kilograms at 1,75m height, but lost a lot of body fat and gained some muscles over the last few months, so I am starting to see a lot more definition on my body. My goal is to have a six pack being visible in about two more months of this regimen.
I am not doing anything spectacular, probably not more than 10 minutes a day of lifting bells, lift ups, etc. I have to admit though, I am not going for the super muscular body builder look. More like lean and defined.
The hardest part is to begin with this. I started with 10 lift ups, and going on. Now I can do 50.
Started with intermittent fasting, but in the meantime I kind of adapted to eating less food and can do now without the fasting (I am drinking a cappucino in the morning, which I need for my mental well being ;) ) and still lose fat.
From my perspective, the most important thing is to keep going with it.
Find a regimen that's acceptable to you, and doesn't rob you of all the fun in life. I still drink a beer or two with my friends a couple of times in a week, for instance, but I keep an overall eye on my calorie intake. Eating rice waffles instead of bread for instance and less carb stuff in general. Which works for me.
tl;dr:
Keep grinding, and you will see results.. (and believe me, these results will make you motivated to keep going)
