KateTT, this is timely as I was sort of just wondering the same thing! I recently pulled out my Leah Sarago's Ballet Body workouts and did the Upper Body one the other day. That particular workout is all body weight in the first half (planks and other torture, ahem, I mean mat work) and in the second half, it uses 2-pound weights that feel like they weigh about a million pounds each by the time you're done.
So here it is, two days later, and I am still
so sore it's ridiculous. For example, my lats and even ribs hurt to touch! I don't get this sore normally lifting weights, and in fact, I cannot get that sore in my lats using my 25-pound dumbbells for rows, regardless of the number of reps I do. So what gives?
I'm definitely considering changing up my routine to fit these types of workouts back in...and my plan looks a lot like what you laid out too! You said it best....too many great workouts, too little time!
