These Are the 14 Low-Impact Isometric Exercises Trainers Recommend to Build Strength

Anna Victoria, NASM-certified personal trainer and Fit Body app creator, told POPSUGAR that she's an advocate for isometric exercises because they increase the strength and endurance of your muscles being engaged. Isometric upper-body strength moves, she said, are her favorite. Here's one of them: lateral arm raise holds.

• Stand with your feet hip-width distance apart. Hold a dumbbell in each hand so your palms face in toward the sides of your body.
• Keeping your core tight and your arms straight, raise the dumbbells toward the ceiling until you get to shoulder height.
• You want your palms to be facing down and your arms to be parallel to the floor.
• Victoria suggests holding this for at least three seconds before lowering your arms back down to your sides.
