Yes, If you are willing to go lungs-on-fire fast or work your muscles until they cry uncle! Experts used to consider ten minutes the minimum chunk you could count as exercise, but that was before Tabata’s (alternating 20 seconds of all-out effort with 10-second rests) proved that just four minutes of high-intensity intervals can increase your cardio capacity and bump up your metabolism for a half hour afterward. BUT you can’t simply go from zero to 60: Warm up with a minute of jumping jacks, butt kicks, and high knees. Then hit it hard for 20 seconds of sprinting, mountain climbers, or burpees. The key to fatiguing muscles to the point where you can see results in that short time is that whatever you do, DO IT HARD! Take a 10-second breather, then repeat the combo for eight rounds total. Just FOUR minutes!
A non high intensity option could be 100 reps of anything you choose, like push-ups or sit-ups, because it’s challenging but not impossible, and it will exhaust your muscles and stimulate growth. If 5 minutes if all you have, make the most of it and be proud. Just don’t make it your regular workout or you’ll miss out on other exercise benefits like toning your entire body, jacking up your endurance, or burning more of your stored fat that even slightly longer workouts will bring.”
I am all about making the most of your time! Sure, we are all busy with a million priorities and rushing around from here and there every day. However, I promise that no matter how busy you are, someone even busier than you are is working out right now. If you look closer, you’ll discover that you do have the time to work out—and with just 5 minutes you can start seeing results by the first day of Spring!
Live Fitt!…Be Fitt!
