Sit-Ups - What it Works
Focus: Abs
Type: Strength
Difficulty: level 3 of 5

仰卧,双膝弯曲,双脚平放于地面,双手置于头后。收紧核心将躯干向上卷起并前屈,直到胸部接近膝盖,然后用同样的控制力缓慢下放还原。双手只是乘客,不是引擎——它们轻轻托在头后,一旦开始拉扯颈部,这一组就不再计数。 仰卧,双膝弯曲,双脚平放于地面,双手置于头后。收紧核心将躯干向上卷起并前屈,直到胸部接近膝盖,然后用同样的控制力缓慢下放还原。双手只是乘客,不是引擎——它们轻轻托在头后,一旦开始拉扯颈部,这一组就不再计数。

锻炼:腹肌(abs)、髋屈肌(hip flexors)、腹斜肌(obliques)

呼吸(Breathing):起身时呼气,躺下时吸气。

常见错误:双手拉扯头颈部、借助惯性猛地起身而非用肌肉力量卷腹,以及不加控制地摔回地面而非缓慢下放。

降低难度:起身时将双臂交叉于胸前或向前伸展,也可以逐步进阶,卷腹(crunches)首先。

加大难度:将下放阶段(lowering phase)放慢至3秒计数,然后继续。蝴蝶卷腹(Butterfly Sit-Ups)将双腿排除在外,或者加入击打动作。仰卧起坐出拳(Sit-Up Punches).

Grateful for your promise in keeping this site accessible and free for people of all fitness levels & goals around the world. Found Darebee some time years ago and used to just save the workouts and then forget about them somewhere in my documents & to do later lists 😅 but coming back to the site this year I loved the organised/simple layout & navigation of the site with full workout video at bottom to see proper form and notes to make things easier or harder depending on your fitness/energy aswell as an extensive exercise library with joint friendly alternatives. I found it much easier to track/check off completed workouts & days on program/plan on dashboard, was more likely to remember & do it + advanced filter made it quick to find a doable workout. As a tiny way to support this site I made account and use the site exclusively for exercises now, will look to donate when I can 🙏🏽 and would recommend it to all I talk to regarding fitness. Thank you Darebee team for the great job you've all done here and keep up the good work. Blessings to you all.

I found Darebee in 2014 and since then I’ve been using it on and off until 2024, when I decided to base all my workouts on Darebee alone. I love the pictures, the variety, the amount of time it takes… I found Darebee in 2014 and since then I’ve been using it on and off until 2024, when I decided to base all my workouts on Darebee alone. I love the pictures, the variety, the amount of time it takes to complete a workout and how you can mix and match if you have a lot of energy or only repeat 3 times if you don’t feel like exercising. The website is awesome and I recommend it whenever I talk about fitness with other people. I cannot thank Darebee enough for how much this project has helped me in having a solid exercise routine and how to deal with exercise when tired, injured or when I don’t have much time.
