Don’t have a lot of time? Who does! But staying fit is critical to not just looking good but feeling good: emotionally as well as physically. The good news is that you can get your body into great shape with these five exercises—that you can do in as little as 15 minutes a day!

  • Planking

    This one can be tough to start but once you do you can increase the time you hold the position more and more. Planking is basically supporting your body on your forearms and elbows—with your back as straight as possible. Ideally, you should aim to hold this position for three breaths, then do a push-up plank (when you elevate yourself from laying flat on the ground). Do this three times.

  • Squat jumps

    This one is pretty easy—and quite fun. From a crouching position, with your fingers laced behind your head, jump and straighten your back. You should be to put energy into your legs and keeping your back nice and straight. Do this 10 times.

  • Mountain climb

    This one is very similar to planking but instead of working on your core and back you will be focusing on your legs: with your arms and back straight bring one leg up to your chest, return it, then switch legs. Like climbing a mountain—get it? Do this 15 times for each leg.

  • Bicycle

    Okay, now lie on your back and do almost the same thing: with your hands behind your head lift one leg (your choice) and then the other up towards your chest. While you are doing this bring your opposite elbow towards the knee you are moving. You want to be focusing on your abs—and always pay attention if your body is complaining. If it is, when you need to adjust your positioning. Do this ten times.

  • Burpee

    This one is bit complicated but really effective: begin by standing then leap up and clap your hands together—from there smoothly drop into a squatting position and from there slide into a plank. Turn this into a sit-up and from there go into another squat and up into another jump. Rinse and repeat, as the old saying goes, eight times.

Ideally, once you have these exercises down, all this should take no more than 15 minutes a day. Yes, it will be a bit challenging when you first start out but if you stick with it they will come easier and easier—and soon you’ll start to see some great benefits in your strength, posture, endurance and even attitude!
