Started in March 2020 joining Founder's Club after using Foundation sitting and standing DVDs in late 2019. How have I improved? No longer using grabber to reach high things in kitchen cabinets, no longer looking for highest arm chair to sit in, able to touch toes on most days, able to lift legs when sitting for core exercises. OH, and I have muscles now. Variety of offerings keeps me interested and moving. Deron is the best personal trainer ever. Leads training that increases ROM, flexibility, endurance, balance, strength in a fun, enjoyable way.
