I bought this a couple of weeks ago but due to holidays and a few issues with my back I still haven't jumped in, I really am dying to do though as the impressions sound good!
I stayed at home for the past 4 weeks due to back issues (lower back pain). Over the last 2 weeks I've been using Ring Fit and it really, really, really helps.
There are some really cool excercises (planks, knee lifts, yoga moves) that work your lower back. After 10 workout days with Ring Fit, my back issues are basically gone.
Of course, my workouts did go hand in hand with physical therapy. But any good doctor will literally tell you to do yoga and/or pilates to help with your back pain.
Take it from someone who used to go to yoga courses in a 130€ per month gym, Ring Fit is legit.
I think my biggest issue with Adventure mode at the moment is that it forces you to use very specific exercise attacks if you want to be optimal. I can't be like "today I want to focus on arms" because the levels I'm doing next might be more focused on abs (or just have a larger mix). Plus the newer attacks you get in each category are so much better than the first ones you get that it doesn't make sense to use the older attacks even if they give you advantage because even newer mismatched attacks would be stronger.
Am in World 5 now and without spoiling everything, I can assure you that you'll be fine.
You will be so overpowered at some point that you can literally toy with the enemies and pick whatever excercise you want.
And trust me, the game will focus on certain areas soon enough. They will also give you modified versions of basic, low level excercises.
After doing this several days in a row, you really appreciate the gameplay elements. I can actually make myself work out just because I'm curious what's happening next. The game is so good at getting you curious and throwing curveballs.
It's honestly my GOTY.
Ring Fit actually makes me look forward to working out, sth I never experienced IRL.
