Apart from the cardio I mean.
I mostly only go to the first circle of machines that the gym-residents don't seem to be very interested in. I'm working up the courage to stride confidently deeper into the gym and use the more popular machines.
I'm particularly interested in one that is without doubt the most popular machine at the gym - you lie face down and bend your legs upwards at the knee. All the teenage boys use that one, but I've noticed the awesome fit older ladies do too. Diagram for reference!
