Is Calixpert suitable for complete beginners or if I am overweight?
Yes, absolutely. Calixpert was built with exactly this person in mind. You do not need to be fit before you start. You do not need any prior training experience. You just need to show up.
The Absolute Beginner program starts from zero. That means no pull-ups required, no baseline fitness level assumed, and no embarrassing entry test. Every exercise has progressions that match where you actually are today, not where you think you should be.
If you are carrying extra weight, calisthenics is actually one of the most effective training methods for fat loss combined with muscle building. You are moving your own bodyweight, which means every session is automatically scaled to you. As you lose weight, the movements get easier and your relative strength increases. The two goals support each other.
We have had hundreds of members start with zero pull-ups, limited fitness, and plenty of self-doubt. Many of them are now doing things they never thought were possible. The program works when you follow it consistently. Your starting point does not determine your ceiling.
