I want to join a yoga group

All the yoga sessions on Instagram will charge me at least 10K/month for only 8 sessions,, that is just too much! Please suggest something cheaper and authentic!

I am a wanna be Calesthenics learner and I need to improve my flexibility and mobility for that purpose.

Preferably evening timings around DHA, Model Town, Johar Town, Gulberg,, but I can adjust. No hard and fast rules.
