Study shows how people waste time exercising

In a study, one group lifted weights for nine weeks (Continuous resistance training – CRT), while another group lifted for six weeks followed by a three weeks rest (Periodic resistance training - PTR). After the first nine week cycle the groups’ results were similar. The cycle was repeated for nine more weeks, and PTR group’s results were significantly higher.

A quote from the study, Comparison of muscle hypertrophy following 6-month of continuous and periodic strength training:

“Increase in muscle cross-sectional area [of muscle] and strength during the second 3-week detraining/6-week retraining cycle were significantly higher in the PTR group than in the CTR group.”

What happens after an extended layoff - an observation

In the aftermath of hurricane Katrina our clients began trickling back into town, and there was a return to normalcy. They began scheduling appointments again. Most had not exercised in anywhere from 6 to 8 weeks.

I expected them to be weaker. I decided to conduct an experiment. I put them through their previous workout, and I did not lighten the weights. I did not offer them any added encouragement, I did not give them a target to reach, and I told them to stop at whatever point they wanted to.  It was a very interesting result.

Most all of the clients got all of their reps. Some were off a repetition, but that's about it. We were doing slow reps, so one repetition can take about 20 seconds. So in total they were off at most 20 seconds on a 90 to 120 second exercise. Within a workout or two they were totally back up to speed.
