Love Jenna, the instructor – she really knows the body and provides very useful corrections when a student does an exercise incorrectly. She provides clear instruction, and mixes up the exercises from week to week so it doesn’t get boring. However, the Saturday mat class is getting too crowded for the available floor space, so we end up hitting our neighbor or the post or the equipment with our limbs sometimes. And the instruction from another (smaller) class in the same room can be distracting.
