DAREBEE Workout: What it Works
Focus: Fullbody
Type: Strength
Difficulty: level 5 of 5
By slowing down a resistance workout the body gets to work the muscles in both an concentric (i.e. flexing) and eccentric (i.e. stretching) fashion. This creates a disproportionate load for each movement which frequently leads to some very interesting adaptations regarding strength and hypertrophy. Arbiter is a workout that uses of all this to help you become stronger and fitter a little faster.

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.
