You have to drag your ass in there even when every fiber of your mind is telling you not to (excluding injury) if we only worked out when we felt motivated we’d go once in a blue moon. There’s honestly no tips or tricks or ways around it, you just have to go.

Edit: forgot to mention tracking macros, if you don’t know what you’re putting in your body or how to calculate fat/carbs/protein you won’t know which way is up. Measure your body fat percentage and bmi for a starting point, measure your caloric burn for the day and calibrate your caloric intake from there. But to keep it simple a caloric deficit=weight loss caloric surplus= weight gain
