@thornbearer As someone who has made this journey: if you're going so hard that you're starting to dread going to the gym, the best thing you can do is slow down and lighten up.
It is vastly more valuable to work out less hard, but stay consistent, than it is to go hard every time. Going too hard too soon courts serious risk of either a) injury, or b) burn-out, both of which are ultimately counterproductive. The person who exercises more gently but maintains the habit will make far more progress over a year than the person who busts their ass for three weeks and then quits.
My best advice:
Give yourself easy wins in the beginning. Work out only to the point where you still have some gas in the tank, and then stop. You may still get some DOMS in the beginning, but you'll also feel a lot more positive about doing it again the next day (or in a couple of days), and that positive reinforcement will lay the groundwork for much bigger gains further down the road. The habit should be your
primary concern in the beginning, and the how/what/intensity should all be secondary. Your body will let you know when it's really ready to do a little more, and you can build from there.
And if you ever get to a point where you start to feel dread or resentment about exercise, it's time to take a step back and consider your intensity, frequency, or whether it's time to try something different.
And know that the vast majority of people who are regular exercisers
do not feel demolished after every workout. Even the long-distance runners and heavy lifters generally only feel pleasantly fatigued; they've just advanced far enough that work that looks impossible to you (and to me) isn't as taxing to them. You can get there, too, but it will take time and consistency. Work out for their intensity level (gentle to moderate for most workouts, heavy intensity only occasionally), not for their fitness level.
Walk, as far as is comfortable and at a speed that is active but sustainable; don't worry about the incline. Maybe do a little bit of simple strength work including exercises like bodyweight squats, wall pushups, modified knee planks, etc. And just focus on fostering the habit of doing something every day, even if that just means showing up for an easy walk 5-6 days per week. The rest will come in time. Good luck!
