2nd Trimester: High Energy | Roots The 2nd Trimester Series of “Practicing for Two” is about maintaining your pre-pregnancy practice or level of fitness while continuing to listen to your body’s intelligence. In the hopes that you’re having lots of days in your 2nd trimester where you’re feeling great, I’m bringing you 3 prenatal strong flow classes that won’t feel that different from any other vinyasa flow class. This practice is all about getting grounded. Life can feel like it’s about to get a bit out of control, but best as possible we stay connected to our roots. Style: Prenatal Strong Flow.
