Master teacher Lee Potter in her third trimester with twins adds her own special wit and playfulness to the Bar Method's pre-natal workout, a long-standing and popular class at its flagship studio in San Francisco. Lee leads you through a series of gentle, safe and challenging moves, including free-weight work, thigh exercises, standing seat-work, and abdominal strengthening performed while propped up on pillows. As Lee puts it, this DVD "will help you feel strong during your pregnancy, will assist you in delivering your baby, and will snap you right back into shape." The pregnancy workout is 45 minutes long. OB/GYN endorced.
