Here’s a great workout for you to try. I did this in my hotel room when I was in Disney a few weeks ago. Its simple, effective, requires little time and space, and pretty much anyone can do it.
do it all as fast as you can. You can even time yourself so you can try to beat it next time.
Push-ups: Do them from your toes if you can, if you need to modify, from that position drop your knees to the ground and go from there. Aim to get full range of motion, which means getting your chest as close to the floor as possible. Remember to keep your body as straight as you can through the movement, don’t bend at your waist.
Sit-ups: Lay flat on your back, knees bent so feet are flat on the ground. I don’t like the traditional sit-up where you put your hands behind your head because for most people this will cause them to flex their neck forward the whole time. Instead, I prefer to keep my hands and arms free, and use them to help creating momentum to complete the movements.
Squats: Stand with your feet shoulder width apart or slightly wider and squat down so your thighs are at least parallel with the ground (further if you can). Focus on keeping your heels on the ground and keeping your chest up. Hold your arms out in front of you to help maintain balance.
Burpees: From standing, you crouch and place hands on the ground and kick legs back to push-up position. From there drop your chest to the ground, then push yourself back up and pull your knees toward your chest back to the crouch position. Then stand and jump. A modification of this is to simply drop down to flat on the ground and get up and jump. The key for these is to keep moving.
