Avoid OverTraining - By Pete Sisco
How to completely and permanently avoid overtraining.
The key to avoiding overtraining and finding your optimal training frequency is to closely monitor the progress you make on each exercise in your workout and identify any sign of slowed or arrested progress. Not progressing in one exercise out of 5 is a yellow flag. Not progressing in two or more is a red flag and means you need to add time off.
Quick Measures of Over Training:
The weight used on each exercise did not increase. Strength training is all about progressive overload. That means you should return to the gym fully recovered and able to lift slightly heavier weights than you did last workout.
The number of reps or the static hold time on each exercise did not increase. If your weight on an exercise did not increase (see above) then your reps or the time of your static hold should have. (Note: recent research suggests that static holds beyond 12 seconds yield less benefit than increased weight with shorter hold times.)
It took you longer to do the same workout. Progress is driven by intensity of muscular output. Intensity is a function of time. So even if you do the identical workout today that you did three days ago but manage to do it in less time, your intensity has increased. But the reverse is also true, so watch out for taking extra time to do the same routine. Lower intensity can not build new muscle.
