Exercise break down

cookeylady

so, I do 30 minutes of walking, then later in the day I do 30 minutes of trampolinging. In October, I will buy me a gym pass and Start going to the gym, I will be biking there, that will be 10 minutes, and I am getting some 30 minute cardio fitness dvd's. I do weight lifting 3 days a week. My question is am I doing too much, if so what should I cut or how should I break this up??
