Any Okinawan Karate style might be to your liking then. The stances tend to be higher/shorter than mainland Japanese karate styles. Also the syllabus for Okinawan Karate styles tend to be much more compact/simple in comparison to shotokan/kyokushin. Uechi ryu has 8 kata for example, while okinawan goju has 12. I get the sense that Okinawan karate seems to be more mindful of long term training which is great - you won't train to failure but you'll still get pushed in a way that you'll still be able to attend the next lesson/class.
Also something I really love about Okinawan Karate is that S&C tends to be a part of classes as hojo undo. Unlike kyokushin/shotokan or other mainland karate styles - in Okinawan karate you do strength & conditioning as part of your karate training - there is time dedicated to it during lessons - the whole point of it is to strengthen/adapt the body for karate training.
The only thing that tends to be missing is that Okinawan styles won't do as much kumite as you'd probably get in kyokushin/shotokan. I try to get my sparring fix from kudo though.
@Hotora86 - It's a very normal thing to train to failure in Kyokushin - most dojos I think will push you to failure. It's great for quick results but not a smart way to train long term because you just pick up injuries and some of them can become chronic problems later on in life. I think also when you reach a certain age it becomes very counterproductive to train to failure - I think it does more harm than good if for example your a 50 year old.
Also I like the way that Okinawan Karate seems to be less cult like than Kyokushin. The atmosphere is more calm (less military like) & you don't osu osu osu to every single thing like a maniac lol.
