FITNESS 50-PLUS: Rest and Recovery
Unfortunately, identifying the right balance of hard work and recovery is the most difficult part of serious fitness training. So it comes to no surprise that most of my clients are much more focused on the exercises I teach to help them reach their goals of rehabilitation, balance, weight management, health improvement, greater overall fitness etc. Paying attention to proper rest and recovery often is being neglected. I guess if one pays for training rest seems a waste. As a trainer and therapist it is my job to ensure that a client/patient is not sabotaging his/her own efforts of improvement and remind them that adequate rest and recovery are an essential part of any work out program and no less important than the exercise itself. Lack of rest in between exercises within a training session and too little or poor recovery on off days will compromise the success of training whether the goals pertain to rehabilitation, health maintenance, fitness or athletic performance and regardless of age. Rest and recovery will however increasingly gain greater relevance and importance as we age. Some of you might have watched the Winter Olympics in Sochi. Norway’s Ole Einar Bjoerndalen (age 40) became the most decorated Winter Olympian of all times. He almost missed the team as he had dropped far down in World rankings in 2012 and only after changing his training and emphasizing rest and recovery did he become successful again. In today’s blog I want to help you better understand the role of rest and recovery and leave you with some tips on how you can maximize your rest and recovery periods to ensure training success.
The role of rest in between sets and different exercises within a training session
Rest in between sets and exercises depend on the intensity of a given exercise (number of reps and work load) the overall demand on the body and the goals of your training . If trying to improve muscular strength endurance/fatigue resistance you trainer will most likely chose light to moderate work loads, high number of repetitions and short (30 seconds or incomplete recovery) rest periods in between sets. If maximum strength is to be improved high to maximum work loads, low number of repetitions, and long rest periods (complete or nearly complete recovery) in between sets are the common choice. Improving aerobic cardio-vascular capacities requires you to train at or near the aerobe-anaerobe threshold for extended periods of time, while improvements of anaerobe capacities require a short high intensity stimulus like a sprint. Rest periods have to be far longer. And yes there are newer methods that have gained great popularity such as High Intensity Training (HIT) or High Intensity Interval Training (HIIT) mostly due to their high caloric expenditure and impact on VO2 that allow for very little or no rest in between exercises. These types of work-outs are typically shorter in total time (15-30 min) and require full recovery on off days to be successful.
Recovery in between training sessions – Super Compensation
Training success relies on the principle of “Super Compensation” which means that training is supposed to stimulate a response that improves the body’s readiness for the next training session and its demands. In order to accomplish “Super Compensation” the work-out has to provide a progressive overload challenging strength, balance, and/or aerobic/anaerobic capabilities etc. In order to ensure optimal results after each session, exercises, work loads, numbers of repetitions and rest in between sets and work outs have to be planned.
Super Compensation requires recovery. In order to improve performance, training has to be timed properly. The best time for the next training session is at the highest level of Super Compensation. Training prior to the climax of Super Compensation limits training results. Training prior to regeneration leads to overtraining and reduced performance. Waiting too long leads to maintenance without improvement. See graphs below for better understanding.
Perfect timing leads to improvement
Overtraining – negative training
Symptoms of Overtraining may include but are not limited to:
- Persistent muscle soreness
- Persistent fatigue
- Difficulty sleeping
- Elevated resting heart rate
- Reduced heart rate variability
- Increased susceptibility to infections
- Increased incidence of injuries
- Mental breakdown
Periodization – variable training intensities and training goals short-, medium- and long term
“Periodization is an organized approach to training that involves progressive cycling of various aspects of a training program during a specific period of time. Periodization is most widely used in resistance program design to avoid over-training and to systematically alternate high loads of training with decreased loading phases to improve components of muscular fitness (e.g. strength, strength-speed, and strength-endurance). This system of training is typically divided up into three types of cycles: microcycle, mesocycle, and macrocycle.” (Frankel, C.C., & Kravitz, L. (2000). Periodization.

Additional ways to maximize rest and recovery on training days and in between
Whether it is between interval bouts, immediately after an interval session, or the day following strenuous exercise, there is compelling research evidence that active recovery is superior to passive recovery (Del Coso et al., 2010). Here are some ways you can speed up and improve your recovery process.
- Post Exercise Nutrition Recovery has three goals, refueling glycogen storage by consuming complex carbohydrates (unprocessed, wholesome grains), offering protein for muscle repair and synthesis (first 45 minutes post exercise are key), and restoring fluid and electrolytes lost through sweat while exercising. Nutrition Recovery efforts should start within 45-60 minutes post exercise.
- Stretch your muscles and/or perform Self Myofascial Release by using a foam roller.
- In addition an ice-cold full body plunge, contrast therapy by alternating hot and cold showers, and icing hard trained muscles right after working out can significantly reduce muscle soreness and inflammation and decrease the existing lactic acid build up, speeding up recovery.
- Ensure a good nights rest with plenty of hours and quality of sleep.
- Low intensity exercises such as walking or light weight lifting on the day following intensive work-outs will increase circulation and reduce lactic acid build up.
- A massage to help with myofascial release, circulation and relaxation can further promote recovery in the days following intense work out sessions.
Despite the fact that recovery is an under-researched topic and therefore not as well understood as other areas of training, we do know that it takes a well thought out training plan and active recovery strategies to speed up and maximize the recovery process, and optimize training results and performance in athletic endeavors as well as in activities of daily living.
I sincerely hope I was able to shed some light on rest and recovery and help you improve your current strategies after finishing your work outs. Please feel free to respond with any comments and questions you might have.
