"Grandma Beckie" is what my grandkids call me. Is it true that I'm a grandma? I love my grandkids, but I'm not a grandma !! I have the best of both worlds; I'm young enough to work hard, but old enough to know better. Changing it up at the gym always makes me sore. I'm trying to convert a long-time marathon runner to weight lifting. She just can't give up the long steady-state cardio. I'm here to tell you that in spite of her long hours of running, she has a layer of fat over her whole body. It's a stress response; your body secretes cortisol which is catabolic to muscle and encourages fat storage. Boo... on that! Interval training is a much better option for cardio and pull out the weights please. My work out today was arms only. I started with 2 exercises, performing 3 sets of 6 reps, two different exercises 3 sets of 8 reps, then 2 more exercises of 3 sets of 10 reps, and lastly 2 exercises with light weight to failure. It felt good. I do about 30 minutes of cardio every day except leg day. That's it; no long, hard bouts of cardio.
