Hi Everyone, I am in my mid 40s and just resumed my martial arts training after 10 years. I find that my flexibility has quite diminished and I am trying to hard to regain it as it is severely limiting my moves, balance, kicks etc. So I am doing some kind of dynamic stretching every day and a harder static stretching regiment (following the routine outlined here: Isometric split progression Just to be clear, I am not really after splits, I just want to be able to kick high, currently i can only kick as high as my hip level. Obviously due to my age i am not making the kind of fast progress i am hoping for. But what really is bothering me is a joint hip pain. This pain is always there, it's not severe , it rather mild an becomes better as i warm up. But it;s always there. When I was younger , i don't recall this kind of pain persisting . I talked to my Sensei and he mentioned that it maybe a mild form of arthritis which is flaring up due to the strain I am putting on it with my frequent stretching. Before I resumed my training, I never had any kind of pain like this, whether going to the gym, skiing or playing tennis, so I find it a bit improbably that it is Arthritis. So my questions are: 1. Could this indeed by Arthritis making stretching more difficult for me? 2. If it is not should I just take a day off not doing any kind of stretching , regardless of how mild? 3. If it is Arthritis , what is the most effective way to still reach decent flexibility with this condition without hurting myself? Thank you in advance for any replies.
