In a study, 65-79 year old subjects were split into two groups; one strength trained once a week, the other twice a week. The results of this study, Comparison of once‐weekly and twice‐weekly strength training in older adults:
“One set of exercises performed once weekly to muscle fatigue improved strength as well as twice a week in the older adult.”
Exercise serves as stimulus to force your body to make a self-protective adaptation. That adaptation will only occur if your body is allowed to recover and compensate for stress placed on it.
As we age are capacity to withstand and recovered from stress diminishes. Exercise too often and you’ll ruin two workouts. If you’re not recovered from the first you won’t improve on the second. It’s a waste of time and effort.
A lot of time is spent in the gym doing the same thing - the same weights, the same reps, the same times - with little to show for it. It shouldn’t be that way; if you are fully recovered you should improve each time.
Through trial and error you can eventually figure it; some never do. At Austin TX Strength Trainers and New Orleans Strength Trainers we pay attention to recovery. We take the guess work out of it to ensure that the improvements are ongoing.
