Bodyweight programs

Three Pillars. One Path.

Calisthenics is more than reps. It's building a foundation, raising the intensity, and mastering hard skills — all with no equipment, at your own pace.

Foundation

Start with the basics. Progressive reps, short rest, steady growth. Whether it's wall push-ups or squats, this is where every journey begins.

Pillar 01

Intensity

Short sessions, real sweat. Conditioning circuits and varied formats that burn calories, build endurance, and keep you coming back.

Pillar 02

Mastery

Technical progression toward harder calisthenics: pike push-ups, L-sits, pistol squats, pull-ups. Long-term, focused, deeply rewarding.

Pillar 03
For beginners

Start Where
You Are

Most people quit because plans are too hard, too random, or too long. Puna fixes that with clear bodyweight sessions, progression that adapts, and momentum you can see — no gym required.

FAQ

Common Questions

No. Every program in Puna is 100% bodyweight — no gym, no dumbbells, no pull-up bar. You train with your body, wherever you are: living room, park, hotel room.

Puna is free to use and supported by ads. The full program library, workout tracking, and core analytics are all included for free. An optional premium upgrade removes ads and adds 2x XP and advanced analytics — but you can train every program without ever paying.

YouTube gives you random videos. Puna gives you 4 structured 8-week programs with adaptive progression, rep tracking, streaks, and analytics. You always know what to do next, and the app adjusts as you get stronger.

Absolutely. Puna is built for calisthenics for beginners — it starts at your level, whether that's wall-supported moves or working toward pull-ups, L-sits, and pistol squats. A short coach quiz asks about your goal and fitness level, then recommends the right starting point. No experience needed.

That depends on your goal and level. Each program offers a selectable weekly frequency suited to its level — from 2 days a week on the beginner program up to 6 on the advanced split. Puna builds rest days into every plan so you recover properly and stay consistent long-term.

TrainRBoost builds focused health apps: Puna for bodyweight training, Cactus for water tracking and hydration habits, and Doudou for baby tracking and family sync. Each app does one thing well.
