@allroads Hey! Health and fitness expert here, been training for over a decade as well.
Your workout regime is way too extreme in my opinion for a novice lifter, and its not sustainable in the long term for even pros without loading up on serious gear (drugs). Your diet is a serious crash-bulk diet with lots of fiber/protein/binders that slow digestion and can cause nausea as well as dehydration if you aren't drinking a lot (fiber/protein draws water out of the blood into the colon). Can also cause gut complications down the road like dysbiosis, bloating, constipation, etc. This, combined with your exercise approach (i.e. multiple weekly full-body workouts) are what top Hollywood actors and bodybuilding competitors do to prepare quickly for scene-shoots and show prep in a matter of weeks. None of it is sustainable in the long run for anyone, and certainly not for a beginner who signed up for a year contract rather than a competitive 3-month body recomposition for the show-biz. Your PT is probably well intended, or new/naïve, or just plain stupid, but either way you need to tell him "Hey, this is too much for me, can we tone it back?" No need to sugarcoat it or beat around the bush, just be real.
It sounds like there was a miscommunication of goals at best. You probably said something about wanting to lose weight or gain a little muscle tone sooner rather than later and he probably took that to mean "the fastest results possible for a total body makeover". It'll be good to sit down,
reiterate your goals (do you want to lose 50 pounds? Get to the female Adonis index in a year? Build larger muscles in your legs? Be specific and make sure its nothing extreme), and let him know that the current approach isn't sustainable for you, and work out where the miscommunication happened so you can get what you're paying for. It's important to remember: if you're a beginner you don't know what you don't know so its hard for a PT to really nail down what you want at first. Just be patient, there's always going to be a learning curve no matter who is training you. Also, PTs use terminology that you aren't familiar with, so you might accidentally use words that have a different meaning to them. They also have to strike a balance between being motivating without making you feel cornered or hopeless. Just remember: you are paying him. You don't have to do anything you don't want to, and the customer is always right. We're not perfect, so you need to advocate for yourself just like in any other situation such as in school or in a doctor's office.
Speaking of doctors, get your legs checked out. Full lower-body numbness isn't something to ignore. Best case scenario you have funky hips that pinch your nerves when you walk at a certain angle or you're dehydrated or have some weird hypoxia going on that caused tingling a few times but won't ever happen again. Worst case scenario: you have early onset MS. This isn't something to ignore, get it checked out. Better safe than sorry.
