yea you have to unlock the longer time feature, just like on the runs. you can run up to 30 mins at a time without a trainer too. i find that harder to do while i'm watching a show though. you could do walking or marching in place too.
this is a leg routine i like to do, there's a lot of squats,lunges you could do a substitute exercise for those, there's a lot that you CAN do though. especially all the floor exercises at the end.
