If you haven't seen my other posts, I have returned to karate after about 15 years. I'm super overweight, but I'm keeping up in class, although not always gracefully. However, tonight's class definitely showed me that I have a long ways to go! Our sensei worked us pretty hard and at one point I felt like I was just flinging my limbs out in front of me trying to get through it. Although I did take some solace in another student stepping off the floor because she needed a breather. I'm training 3 nights per week at the dojo (about 1 hour and 15 minutes each), and last week I started going to a 50 minute college class 2 nights per week - although the college class is pretty slow paced and is really more about working on technique for me than fitness. While my fitness level is certainly improving through this alone, I feel like I need to 1) do more cardio so I stop getting wiped out during kihon, and 2) get stronger legs. What do you all recommend I do? I have access to a good gym at my university and it basically has everything. I was thinking I might want to do some swimming on non-dojo days. Would it be a good idea to do some additional workouts on dojo days? Maybe some cycling or something? I'm afraid of over doing it and having no energy for karate, though.
