I’ve been doing the Wellen program since November. I purchased at a discounted price of about $69. It is set up based on your own fitness level and moves progressively. Sessions are supposed to be done 3x per week. I am finding it good for me, as it is easy to commit to the 30 minutes each session. You use whatever equipment such as hand weights or elastic bands you may have at home plus a chair and mat. It combines gentle and safe tai chi, Pilates, balance and strength movements. You can share the workouts with a friend for free.
