Well this fat middle-aged man kept up with two 20-something kids at the police fitness test just last month. One was athletic and in great shape, the other less so but recently out of the army and in good shape. I surprised myself how well I did, but having the 2 others there to motivate me (competition).

I'm highly self-motivated and don't need a personal trainer to be in good shape, which is all I'm looking for. After leaving the PD, I slacked off a bit, then started lifting again but with no cardio work. I'll start doing cardio again and see what the scale says in a month.
