Hallux Rigidus

I was just wondering if anyone out there has experience with hallux rigidus?  I've had it for a couple years and it hasn't hindered me too much,  but the bump on my toe is getting bigger!

Also, I really like the 6 week beginner training plan, but I don't have an hour and a half a day to exercise.  45 minutes a day is much more realistic.  Should I concentrate mostly on the cardio or balance with the strength exercises?
