Overall , home-based resistance exercise  can improve both strength and functional ability , but the improvements are generally small .
The intensity of the exercises might not progress sufficiently enough to produce large improvements in strength as a result of less supervision or a lack of motivation to increase the intensity further
Home-based resistance exercise is commonly used for individuals who might not have access or the ability to use traditional resistance exercise .
However , the extent to which home-based resistance exercise can improve both strength and functional ability has not been investigated in healthy older individuals using a systematic analysis .
Exercise--it's never too late: the strong-for-life program.
OBJECTIVES This investigation determined whether an in-home resistance training program achieved health benefits in older adults with disabilities . METHODS A r and omized controlled trial compared the effects of assigning 215 older persons to either a home-based resistance exercise training group or a waiting list control group . Assessment s were conducted at baseline and at 3 and 6 months following r and omization . The program consisted of videotaped exercise routines performed with elastic b and s of varying thickness . RESULTS High rates of exercise adherence were achieved , with 89 % of the recommended exercise sessions performed over 6 months . Relative to controls , subjects who participated in the program achieved statistically significant lower extremity strength improvements of 6 % to 12 % , a 20 % improvement in t and em gait , and a 15 % to 18 % reduction in physical and overall disability at the 6-month follow-up . No adverse health effects were encountered . CONCLUSIONS These findings provide important evidence that home-based resistance exercise programs design ed for older persons with disabilities hold promise as an effective public health strategy
