YOU MADE IT!
Your next assignment is to take a week off from strength training (but keep up your cardio by walking, running, or biking). You've earned it, and it'll help your muscles repair and get ready for your next challenge. After all, "this isn't the end," says Rosante. You're fit enough now to do whatever you want. Starting this routine over again from the beginning is one option: If you work to improve your times, you'll get stronger, and the variety built into it will keep your fitness from plateauing. But why not sign up for that boxing class you've been intimidated by, or tell your coworker you can join the office kickball team this year? You're in a whole new place now— take advantage and amaze yourself.
