Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period. If you’re looking to improve your muscular endurance without the use of expensive equipment, floor exercises are your best bet. Here are the 9 best floor exercises that you can do at home, which will help in boosting your muscular endurance:

1.Planks: Start by getting into a push-up position on the floor. Bend your elbows at 90 degrees and rest your weight on your forearms. Your body should form a straight line from shoulders to ankles. Engage your core by sucking your belly button into your spine. Hold this position for as long as you can maintain proper form.

2.Push-Ups: Position yourself face down with your hands slightly wider than shoulder-width apart and your feet together. Lower yourself until your chest almost touches the ground then push yourself back up to the starting position.

3.Squats: Stand with feet a little wider than shoulder-width apart, hips stacked over knees, and knees over ankles. Extend arms out straight so they are parallel with the ground, palms facing down. Sit back and down like you’re sitting into an imaginary chair.

4.Mountain Climbers: Start in a push-up position, with your hands shoulder-width apart and back flat. Pull one knee into your chest while keeping the rest of your body in the plank position, then switch legs quickly.

5.Lunges: Stand tall with feet hip-width apart and take a big step forward with one leg while lowering your hips toward the ground until both knees are bent at about a 90-degree angle.

6.Leg Raises: Lie flat on your back, legs straight out in front of you. Lift them up towards the ceiling until they’re about perpendicular to the floor, then slowly lower them back down without letting them touch the floor.

7.Russian Twists: Sit on the ground with knees bent and feet off the floor (you can keep them on the ground for stability). Lean back slightly and hold hands in front of you. Twist torso to one side, then rotate to touch the ground on the other side.

8.Bicycle Crunches: Lie flat on the floor with lower back pressed to the ground; place hands behind head, interlocking fingers for support. Bring knees in towards chest-like pedals of a bike and alternate touching elbow to opposite knee by twisting at the waist.

9.Burpees: Begin in a standing position before dropping into a squat with your hands on the ground just outside of feet. Kick feet back so you are in plank position, drop to do a pushup, return to plank then kick feet into squat before jumping up with hands reaching overhead.

Incorporating these exercises into your fitness routine will not only help improve muscular endurance but also overall body strength and cardiovascular fitness. Consistency is key, so aim to perform these exercises regularly while gradually increasing intensity or duration to continue challenging yourself as you get stronger!
