3 Exercises That Are Equivalent to 100 Sit-Ups

Sit-ups are a classic exercise for strengthening and toning your abdominal muscles, but they can be tough on your lower back if not done correctly. If you’re looking for some alternatives to sit-ups, here are 3 exercises that can provide even better benefits:


  • Planks are a great exercise for strengthening your entire core, including your abs, obliques, and lower back.
  • To do a plank, start in a push-up position with your hands under your shoulders and your feet hip-width apart.
  • Hold this position for 30 seconds to a minute, keeping your body in a straight line from head to heels.
  • You can also try variations such as side planks and mountain climbers to challenge your muscles in different ways.

Russian twists:

  • Russian twists are a great exercise for targeting your obliques and improving your overall core strength.
  • To do a Russian twist, sit on the ground with your knees bent and your feet flat.
  • Hold your arms straight in front of you and lean back slightly.
  • Twist your torso to the right, then to the left, and repeat.
  • You can make this exercise more challenging by holding a weight in your hands or by extending your legs straight out in front of you.

Bicycle crunches:

  • Bicycle crunches are another excellent exercise for strengthening your abs and obliques.
  • To do a bicycle crunch, lie on your back with your hands behind your head and your knees bent.
  • Lift your head and shoulders off the ground and bring your right elbow towards your left knee as you straighten your right leg.
  • Alternate sides, bringing your left elbow towards your right knee as you straighten your left leg.
  • Continue to pedal your legs and twist your torso to work your abs and obliques.

As with any exercise, it’s important to warm up before starting and to focus on proper form to avoid injury. You can also increase the intensity of these exercises by adding weights or increasing the number of reps and sets.
