Stressed out in Southwark?

I spent the last hour or so searching for yoga studios and using the nifty journey planner to determine how long it would take me to travel from the flat we hope to get on Tower Bridge Road and Maltings place near the London Bridge Underground stop to various yoga centers in London. Of course, I could have spent this time actually traveling to a yoga center or practicing at home, but I'm a self-diagnosed Kapha and sometimes I just like to sit and poke around online. Curiously, all of the studios I checked (Light CentRE, yoga place, islington yoga, all three triyogas) are approximately 20 minutes away, except for Jivamukti which is almost double the travel time of the others. Sadly, for both my wallet and my schedule, there is only one yoga studio (Yoga Globe House) I could find on the Southwark side of the river, meaning and Underground ticket would not be necessary. Do I sense a business opportunity in my (hopefully) new 'hood? If I am wrong, please do send the names of other studios my way.  I look forward to trying them all and reporting back, once I get settled with a flat and a job.
