Jung-Seok, L et al. J Exerc Rehab Oct. 2016.
The benefits of strength exercise plus walking was found to be more effective for overweight cLBP patients vs. just strength training. The exercise was performed twice a week, 50 mins per session for 12 weeks. All variables were improved but the fat-loss and pain levels were more improved by the addition of strength-training plus walking.
This study further supports the suggestion that if we are using rehab in our clinics, 2-4 months of 2-3x per week sessions is both reasonable and clinically expedient for all of the variables which constitute successful outcomes.
