Hi Lizzie,
I know there are plenty of people in the wide world who would disagree with me, but if I were you, I'd probably focus my upper body work on heavy lifting. Gaining muscle will shape your arms (and, holding calories constant, you'll lose fat there, too, since muscle is darn hungry!
)
And hey, no shame in the fly-by-the-seat-of-your-pants rotation! Though ultimately following a program isn't a bad idea. Having said that, life's too short to do workouts you don't feel like doing. Have you done STS?
Honestly, I don't know about strength gains in this rotation -- it's only been two weeks and I haven't repeated any workout once, so I've had no opportunity to observe strength gains (since rep range, rests, yadda yadda are always changing). Now, I've
definitely developed skills over time via heavy lifting. I can do two unassisted pullups (woo woo!) and way more pushups than I ever could before (though I'm invariably humbled by GS Chest -- ha!).
I'm actually just about to start a new strength training program where I'll be lifting heavier than ever with lower reps -- psyched to see where that takes me in terms of strength gains!
Hope you enjoy the one-body-part-per-day lifting rotation if you decide it's for you. Keep me posted! Sounds like you're on the road to success. Just keep being your awesome ninja self!
And sorry to hear about your mom's negative comments. That's tough. Just remember that your body is beautiful THE WAY IT IS! Rock those tanks without apology. And if you do some heavy lifting, you can sneak some quality flexing moments in the bathroom mirror!
Be well,
Roz
Oh and a P.S. (with am embedded P.S.), I read
this awesome article on Girls Gone Strong last week, but my favorite quote is this:
"P.S. With strength training, you will gain muscle. “Toned” and “Gainz” mean the same thing."
