What muscles does the crunch work?

Dumbbell crunches are a great alternative for cable crunches. Cable crunches are safe and effective, making them a mainstay exercise at the gym. The advantage of using cables is that they are constantly providing tension because they can pull in different directions than free weights, which can only pull down.

Cable crunches can enhance your core strength and stability . Cable crunches activate muscles throughout your upper abs and lower abs, including the rectus abdominis (the six-pack ab muscle). A strong core is essential for performing more challenging compound exercises like the deadlift, bench press, and pull-up.24 Şub 2022

Like situps, crunches help you build muscle. But unlike situps, they work only the abdominal muscles . This intense muscle isolation makes them a popular exercise for people trying to get six-pack abs. This also makes them ideal for strengthening your core, which includes your lower back muscles and obliques.
