Today is the last day of the Clutch Life trainer—or is it? If you're enjoying yourself and seeing great results—which I know you are—why stop? There's a reason this trainer is called the Clutch Life 24/7 Trainer.
Start over again at Day 1, or just step back to Week 3 again if you prefer. Whatever you decide, be sure to keep the intensity high. Add rounds, reps, and work time, or decrease the amount of rest you take. Every week should be more difficult than the week before.
If you'd like to do something different, try another free trainer. No matter your choice, make sure you keep moving your body and making good nutritional choices. After all, fitness isn't a four-week mission; it's a lifelong journey!
