Hello, I am not so much of a regular practitioner as I have work and some personal commitments which deter me to seriously train in Japanese Martial Arts. For the past 6 months I learnt only katas and I never got the chance for sparring and randori. On top of that most of my time is spent at work or in other personal commitments. so, I really don't have much time to train for myself. Just yesterday my sensei told me that I would be having exams in 2 weeks. I am in such a predicament. Is there any way where I can catch up the lost time and also regain my endurance so that I can be fit for exams in 2 weeks?
