Phil. Yes, you have come to the right place for motivation. The reason most of the people on this forum got a resurfacing was so that they could get back to the sports we love. I had my first hip resurfaced when I was 57, and got right back to skiing 7 days a week all winter; and surfing, windsurfing, and playing tennis every day all summer. At 67, I just had my other hip resurfaced 4 months ago, and have been working out for 2 to 4 hours every day so that at six months post surgery, I can return to that same schedule.
It does take some time to get our hips in shape for any new activities. Dr Gross says that starting at six months, I can do anything I want, as long as I approach any new activity gradually. 33 years old is way to young to be slowing down. You have decades of athletic activity ahead of you. I have ski students in their 80s who are still charging, and work hard at staying in good shape. If you want it, that can be your future as well.
I liked your idea of working with a personal trainer, which if nothing else, will provide you with a regular kick in the pants to get your motivation going. The one thing I would suggest is to make sure that whoever you work with, whether it be a trainer or a PT, is familiar with resurfacing, and how to work with that. You don't want to hook up with some gung ho guy who just tells you to push through the pain while your hip is building back its strength and range of motion. You want to be pushed, but with some awareness of how to work with a resurfaced hip as you build back to top form.
If you want to make sure that it is okay to start pushing things, I would suggest having a check up with a resurfacing surgeon, hopefully the fellow that did yours. Explain to him your plans, and see if he approves. I would emphasize that it needs to be with a resurfacing surgeon, and not someone who does total hips, since the restrictions would probably be quite different.
Good luck, and hope this provides some of the desired motivation.
