You can train everyday without physical effort if you wish. Standing In the checkout line Irimi... Working around the House Tenken...Cutting yard work...Develop an Aikido Mindset...Most good athletes are always training this way and it ensures rapid technical progression when you learn how to develop your "Aikido" mind. Another Terry Dobsen story I enjoyed is the one where he tries to keep up with O'Sensei at the train station. LOL It seems O'Sensei was always practicing too.
