I get tickled when they hop on a cross trainer next to my girlfriend, who is 61 years old, with the body of a 25 yr old....seriously. She's hauling azz on the cross trainer ( eliptical) and she'll do it, non-stop for 40 mins easily. These young guys hop on one next to her and they last 10-15 min at most and they are on level one or two, when she's on level 19. No one in the gym can keep up with her.( she's been doing it for 14 years now) It's hilarious to watch. I'm usually nearby and she winks at me, knowing what I'm thinking. BTW, she's 5-2, 115 lbs.
We are all about reps, not weight. Bulking up isnt our thing. Did that years ago. Staying strong and healthy is. If you dont do your cardio, you are pizzing in the wind. Want to see how weak you are really are? Get on that eliptical at level 19 for 40 min., then hop on the treadmill at a 7% incline at 6 MPH for another 30. Then go lift. If we old farts can do it, so can you, eventually.
