@igortachkent Totally makes sense, it can get real hard with long work hours + family at home, you have responsibilities on the plate and finding exercise time can get challenging. What I would do if I was in your shoes, is build a little at home set up, something you can use in the garage or in the living room, whatever space you have available to you. You can get a lot done with a couple of dumbbells, even a kettlebell, even more if you have both items. Resistance bands also help and are super convenient to keep around and pick up and use.
I echo what everyone else has said about discipline vs motivation also, motivation really comes in waves, some waves are huge and some waves are barely a trickle in the water. Discipline and habit forming is the only way to get consistent with workouts and exercise. You can make the process easier by doing what I recommended above ^ and building around what you have available to you, what time and what space. It’ll be a lot easier and realistic to get a 40 min at home workout done with some weights you picked up at Walmart, then it would be to commute to a gym and get a workout in, and then commute home.
This is a good way to start, and get the habit and discipline formed. Don’t bite off too much too soon, work your way up there. Mentally it’s important to remember what you want and what you need to do to get there, that’ll hopefully push you along as well.
Best of luck to you and you got this!
