Really tough session tonight. Sensei did his old trick of asking if we wanted a hard lesson or not. Of course, we said yes. And sure enough, it was hard. Maybe the hardest yet - pretty relentless with press ups, squat thrusts, burpies, etc., all mixed in with some oitsuki, maegeri and shuto uke practice.
But I was pleased to find I was able to get through it relatively unharmed. My fitness is definitely improving. Main things to work on are keeping the front foot straight when in back stance, and making sure I lean back in maegeri.
