“I love how Beth engages during the workout, letting you know how you should be feeling each move and where you should feel it. Making the little adjustments to each move really helped me feel the exercises where I should, and finally took my thighs out of my squats and lunges and put the work into my glutes. I look forward to my half an hour every day with Beth, and the time flies.”
