The decline twisting sit-up is an abdominal and oblique exercise made to strengthen your core and build muscle. It’s a great exercise for intermediate to advanced lifters because it’s moderately challenging but very effective for its intended purpose. You’d only need your own body weight to perform this exercise but you can also increase the difficulty by holding a weight plate, dumbbell, or medicine ball.
Now, the abdominal and oblique muscles play a big role in complete body stabilization during any form of weight training, so it’s imperative to strengthen these muscles. But you don’t need to get too complex when it comes to ab training since the core does receive a lot of stimulation during lower body compound movements.
So, the decline twisting sit-up is a perfect isolation exercise when you want to develop the core muscles directly.
