If you're looking to lose weight you're better off getting a dietician or cooking classes instead of a PT

You can lose weight without stepping foot in a gym. You only burn 5% of your calories through exercise, majority of your ability to burn calories is down to your genetic metabolism. Try and run off a kit kat on a tredmil and you'll see how unreasonable trying to exercise off a bad diet is. You can bust your ass at the gym, if you're in a calorie surplus you won't see proper results.

PTs are great if you want to gain tone, muscle, or hit new PRs. But majority of fat lose happens outside of the gym beyond their dictatorship. You're better off investing in a cooking subscription service like hello fresh, Getting a dietician or learning new cooking skills.

That dosnt mean don't exercise, but you can't pin point fat lose. Crunches won't get rid of belly fat, curls won't get rid of your bingo wings- all of these exercises are for toning that you can only see if you're under a certain weight. So if you're busting your ass at the gym wondering why you're lifting crazy but not seeing results, (maybe you've even gained weight) the results are there, maybe you've even increased in muscle causing the scales to make you think you've gone backwards, it's just you've gained muscle and not lost fat so all the stuff you've been working on is hidden.

PTs can tell you how to calorie count, teach you about macros but they're not cooks. They can't give you step to step guides on how to make the healthy food you like. Alot of them don't even have a diet that the average person outside of the fitness industry would regard as sustainable. Some of them eat food like plain rice and white chicken that would send the average person into a state of depression.
