I'm a Trainer, and This Is My Favorite Exercise For Strength Training and Weight Loss

To make a plank more challenging, you can try a variety of foot and hand positions. Balancing on one leg is the first variation I recommend to clients, and then you can move on to more advanced plank positions like alternating shoulder taps, alternating leg lifts, alternating knee to chest, walking plank, Superman plank, and hip dips. Each plank hits a variety of muscle groups and works on balance and coordination.
