Train Away the Pain -  Calgary exercise expert shares message of pain-free living  through her DVDs    Denise Beatty knows the struggle  of living in chronic pain.  The Calgary-based personal  trainer and exercise physiologist  was in two serious car accidents  within two years in the late 1990s.  The second accident -- a headon,  high-speed collision by  Canada Olympic Park in 1996 --  left her with extensive knee, hip,  neck and back injuries.  It also left her in tremendous,  unrelenting pain down her left  side.  Yet, throughout her recovery, Beatty, who was working at the University of  Calgary at the time, kept working out, doing her special brand of core  stability exercises.  Using the balance ball, resistance bands, weights and compound exercises  that engage multiple muscle groups at the same time, Beatty found relief  from her pain as she built up overall muscle strength.  She also ended up whittling herself to a lean shape, losing 30 pounds and reducing her body fat by eight per cent. "The exercises saved me  that's for sure," says the 32-year-old.  Now Beatty hopes to spread the message of pain-free living, and pain-free fitness and exercise, to the masses. Beatty's personal program which she has named the Fitness Fix and has adapted over the years is now available on three new fitness DVDs she produced in June 2006.  The Fitness Fix, which stands for Functionally Integrated Training with Fun Innovative Exercise, is focused on building overall core strength, balance and endurance to prevent exercise injuries in the first place or help people recover from injuries.  The three DVDS beginner, intermediate and sports conditioning were filmed outside at Nakoda Lodge, a hotel and conference centre on the Stoney reserve west of Calgary, last summer over four days. Each features Olympic skeleton athlete Lindsay Alcott.  Unlike other exercise videos, Beatty's has no background music. Instead,  throughout each video she talks about body mechanics, proper alignment and injury prevention as sh --The Calgary Herald Feb 8 - 2007
