if your workout is about weight loss:
watching out for your diet is just as important as working out. first you should have a check-up on your blood sugar and insulin levels. if you're good (or especially if you have IR), try going for a lowcarb / keto diet.

this all above is what worked for me the best. why am i still fat? well, i am weak-willed and it's an easy habit to break (because carbs = deliciousness), but once you get in the flow, it's actually very easy to maintain. i did it VERY seriously twice in my life, all the time i lost about 8 kg (~17 lbs) per month, only from fat, Not by muscle / water loss!
it is not a diet, it requires a total change of lifestyle.
