Most of my sparring partners are 2-4" taller than me (yes, we have a guy who's 6'3" and fights at 170). Since I have relatively long legs for my height, I tend to try and close the distance with kicks, but if I'm with someone decent (like 90% of the people I train with) they pretty quickly catch on, but I'm too far out of range to setup my kicks with hands.
When I talk to people about this I get general responses like timing and angles... well yes. But what I'd really like are either some principles, some foot work to think about or maybe some good video examples.
This end up being less of an issue in an actual fight (in my very limited experience with those) since they don't know, but it still feels like a real weakness in my stand-up. Most of the time I'm doing American Kickboxing rules, or Muay Thai rules, hopefully within the year I'll be doing MMA too, I just started specifically training to incorporate the stand up and ground, so we'll see how that goes.
By the way, my coach is great, but right now he's focused on the pros and more serious armatures who are within a month or two of their fights. I'm sure when it's over, since that's to most critical and obvious hole in my game, I'll get some more instruction on that, but in the meantime, I'd appreciate any suggestions.
