I am a pt and exercise referral specialist and from all my years of research, I can say that there is a huge amount of misinformation on the internet regarding nutrition and exercise so please if anything, steer clear of it because a lot of stuff I see just doesn't add up to the science! I actually left university midway through my second year to get my health on track. I was very overweight and suffering from a chronic condition and paying for a pt was definitely on my mind as I was clueless. My partner who is a PT too helped me and although the help was free, it was the best thing I ever did. Having pt sessions isn't just paying for exercise and nutrition advice, it sets you up for life and helps you form healthy habits which help you both physically and mentally and prevents the development of health conditions further down the line. So would I say it's worth it? Yes definitely as you can't put a price on health. It depends how much you can afford but me and my partner offer online coaching at a cheaper rate and are quite flexible so that might be an option for you if you're short on cash.
