So, what do you like? If possible, what is the most "bang for the buck"...that doesn't take forever...like a good 15-20 min routine?
Disclaimer--I HATE HATE strength and core training. Hate it. It's the most boring thing EVER for me. But, it does work and I notice the difference when I do it vs. when I don't.
Just looking for ideas to keep things fresh, etc. :)
