Awesome effort you put into making quality workouts/plans/programs and that you still continually update and add new ones. Grateful for your promise in keeping this site accessible and free for… Awesome effort you put into making quality workouts/plans/programs and that you still continually update and add new ones. 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.
