Not everyone can do planks as they are quite difficult, now you do not have to do them anymore.
Planks are often touted as a major exercise for the cores.
However, a lot of people just hate them as they are very stressful.
Others dislike planks because they can cause severe injuries if not done properly.
Thankfully, there are other exercises that guarantee a strong core which is very important because it keeps your pelvis, lower back, hips and abs working together in sync.
The following three exercises should be done two to three times a week for maximum results.
Steam engines- Stand with feet shoulder-width apart, hands behind your head, with fingertips lightly touching each other (just as you would do for a crunch on the floor). Keep your elbows out to the sides. Engage your abdominal muscles as you rotate your upper body and try to touch your right elbow to your left knee 20 times. Then, repeat with the left. Do the same 19 times on each side, then 18 times, 17 times, 16 times and so on, until you reach a single rep on each side.
Side hip-ups- Lie on your right side and prop yourself up on one elbow so your shoulder lines up with your elbow. Your hand should be in front of you. Keep your legs straight out to your side, feet stacked on top of one another. Place your left hand on your left hip. Slowly raise your hips by engaging your core and pushing against the floor with your feet until your body forms a straight line. Do 10 on each side, or as many as you can do in good form.
Pikes- Place yourself in a push-up position. Keep your core engaged as you roll up on the tops of your sneakers and hike up your hips toward the ceiling, forming an upside down "V." Pause, then slowly make your way back out to starting position, and repeat. Aim for 10 or more reps, or as many as you can do while maintaining good form.
