With gyms closed, at-home workouts are the new normal.

But it isn't always easy to get into a workout routine at home.

People searched for ab and core workouts above all else on the free Nike Training Club App for the week of April 20. Nike Training Club members logged 66,000 minutes of crunches and 890,000 mountain climbers, according to the company.

"It has been absolutely incredible to see how many people have been leaning into digital apps to get themselves staying sane and healthy throughout this time," Nike master trainer Kirsty Godso told "Good Morning America."

If you're looking for a place to start, think core. Godso shared seven moves to strengthen the core that you can do at home with no equipment.

For a complete workout, do each move for 45 seconds and rest for 15 seconds in between.

1. Dead bug

Start by laying on your back and putting your legs in a table top position. Alternate extending one arm and leg and return to tabletop position.

2. Criss cross

From tabletop position, place both hands behind your head. Tap your left elbow to your right knee and reverse.

3. Heel tap

In tabletop position with your hands behind your head, flex your feet and lower your heel to the ground. Return to tabletop position and repeat alternating feet.

4. Leg lower

From tabletop position, extend your legs into the air. Lower your legs 45 degrees and return. Keep your core tight and raise your head for added difficulty.

5. Reverse crunch

Lay on your back with your hands on the floor by your side. Bend your legs so your heels are close to your body and lift your knees towards your chest. (Your body should leave the floor slightly.)

6. Bear hold

Start on your hands and knees with your toes curled so they're touching the ground. Lift your knees so they're a few inches above the ground and hold.

Looking for an extra challenge? Alternate tapping each shoulder while remaining in the same position.

7. Forearm plank with a hip dip

In a plank on your forearms, slowly rotate your hips from side to side while keeping your core tight and engaged.

For even more exercises, the Nike Training Club app has more than 185 online workouts and is free for U.S. consumers.
