I started weight training and then stopped because I found my self having difficulty brushing my teeth, doing Aikido, and fending off babes.
Actually I stopped because of two reasons. Work is tough and and non-Budo nights by the time I finish I want to get home to supper rather than do something so totally boring as a weight routine. But all things considered I really should get back to it. Last time I had a whole routine worked out but it took too long. Maybe this time I will choose something that will take no more than 20 minutes.
One of my Aikido students is into weight training - one of my best Aikido students I might add - and perhaps he will help me out.
One thing I did notice is an Aikidoist putting down weight training yet doing bokken swings ad nauseum. Same function really.
