Side Jacks - What it Works
Focus: Fullbody
Type: Cardio
Difficulty: level 1 of 5

双脚宽站,一只手叉腰。将重心移向一侧,对侧手臂大幅度画弧向上越过头顶,身体微微向伸展方向倾斜,然后流畅地过渡到另一侧并交换手臂。保持节奏轻松连贯,像节拍器一样左右摆动。这是适合那些膝盖想要有氧运动但又不想跳跃的日子所做的开合跳变式。 双脚宽站,一只手叉腰。将重心移向一侧,对侧手臂大幅度画弧向上越过头顶,身体微微向伸展方向倾斜,然后流畅地过渡到另一侧并交换手臂。保持节奏轻松连贯,像节拍器一样左右摆动。这是适合那些膝盖想要有氧运动但又不想跳跃的日子所做的开合跳(jumping jack)变式。

训练动作:肩部(shoulders)、腹斜肌(obliques)、股四头肌(quads)、小腿(calves)

呼吸:保持稳定而有节奏,与身体的左右摆动同步。

常见错误:弯曲伸展的手臂,使弧线无法完全打开;躯干向前塌陷而非向侧方倾斜;双脚平放,让双腿不再参与动作节奏。

降低难度:双手叉腰,只需将重心左右转移,或者放慢节奏。

增加难度:在换边时加一个小跳,或者继续半开合跳(Half Jacks)然后开合跳(jumping jacks)对于高冲击版本。

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.
