A Deep Dive
OCTOBER 2023
Dearest Readers,

Fall is here and the leaves are bright
Our sky is fading, lack of light

Hallow's Eve fast approaches
Time to train hard with your coaches

Routines are settled, muscles GROW
Just in time for falling snow

Gains in power, pose to flex
Here's to you and here's to PEX!

Happy October!
Happy Pumpkin Season. 🎃

Interval Training and Its Placement in Strength Workouts:
A Deep Dive
By: Mike Campanella

Interval training is a type of training that alternates between high-intensity bouts of exercise and low-intensity recovery or rest periods. In my opinion, interval training is a more effective and efficient method of training for cardiovascular fitness, especially in the context of a 60-minute personal training session, when compared to more traditional forms of aerobic fitness training.

Integrating interval training alongside strength training can combine the best of both worlds, simultaneously improving cardiovascular fitness, muscular strength and hypertrophy, as well as increasing fat burn, and improving overall work capacity. However, the placement of the interval training – whether at the beginning, middle, or end of a strength workout – can influence the adaptations and outcomes. Let’s explore the benefits and various training adaptations of each scenario.
1. Interval Training at the Beginning of a Strength Workout

Benefits

Priming the Body: Starting with interval training can act as an extended warm-up, increasing heart rate, core body temperature, and enhancing blood flow to muscles.

Maximal Effort: Engaging in conditioning first can allow athletes to reach higher intensities, and exhibit a higher amount of effort, considering the muscles are fresh. Increased effort and output could potentially improve cardiovascular adaptations.

Mental Preparedness: Tackling the toughest cardio segment first not only sets a positive tone for the rest of the workout but also fortifies mental resolve. By navigating through the hardest part upfront, clients often feel a sense of relief and confidence, aware that they've overcome the most demanding segment of the session.

Adaptations

Improved Cardiovascular Fitness: With minimal fatigue, and fresh muscles, clients will be able to exhibit maximal effort during the interval portion of the workout, which can challenge the cardiovascular system more effectively.

Enhanced Fat Utilization: Given the intensive nature of interval training, the body might access fat reserves sooner during the strength session, especially if the vigorous conditioning segment has depleted readily available energy substrates and muscle glycogen.

Enhanced Opportunity for Motor Skill Development: Starting with cardio means muscles and the nervous system are already somewhat taxed when transitioning to the strength component. This could necessitate lighter weights and greater attention to form. This heightened focus on technique might stimulate greater neuroplasticity, fostering better retention and mastery of movement patterns.
2. Interval Training in the Middle of a Strength Workout

Benefits

Strategic Structure: Incorporating the conditioning phase in the middle of the workout not only breaks the monotony but also provides a strategic distribution of energy and focus throughout the session.

Optimized Intensity: By pre-fatiguing muscles with initial strength exercises, the subsequent interval phase can be approached with greater intentionality, maximizing the challenge and benefits of each set.

Comprehensive Muscle Engagement: The initial strength phase, focusing on fast-twitch fiber activation, ensures that more slow-twitch fibers will have to participate in the interval section of the workout, leading to a holistic workout that targets a broader range of muscle fibers.

Adaptations

Enhanced Muscular Endurance: Over time, training in a pre-fatigued state challenges the body to adapt and perform under stress, potentially improving endurance during prolonged activities or events.

Adaptive Energy Efficiency: Regularly practicing this structure can lead the body to fine-tune its energy expenditure and efficiency, better navigating the alternating demands of strength and cardio exercises.

Neuro-Muscular Synchronization: Repeated exposure to varied fiber recruitment could foster improved coordination between the nervous system and muscles, fine-tuning movement patterns and boosting performance.
3. Interval Training at the End of a Strength Workout

Benefits

The “Finisher” Effect: From a psychological standpoint, performing the conditioning at the end offers tangible benefits. Most clients, after completing the hardest part of the session, will depart with a profound sense of achievement. Exiting the session having expended all their energy not only validates their complete commitment but also ensures they perceive maximum value from their investment in the workout.

Maximize Muscle Growth: Performing the conditioning at the end of the workout means strength exercises can be performed without pre-fatigue from intervals, potentially leading to better muscle strength and hypertrophy gains.

Improves Recovery: Finishing with higher intensity intervals typically necessitates an enhanced cool-down period post-interval training. This can lead to faster lactate clearance.

Adaptations

Increased After-Burn: Performing the conditioning at the end, as a metabolic "finisher," will ramp up the heart rate and increase calorie burn to complete the session. This environment is conducive to amplifying EPOC (Excess Post-exercise Oxygen Consumption). Intervals executed after the strength component may particularly elevate this after-burn effect, prolonging the benefits even after the session is over.

Enhanced Anaerobic Capacity: When you engage in high-intensity intervals, especially after preceding strength training which might have fatigued some of your energy stores, the body is forced to rely more on anaerobic systems. The anaerobic energy system, specifically the anaerobic glycolytic system, is utilized during short bursts of intense activity, providing energy when oxygen is limited.

Improved Mental Toughness: Pushing through intervals after a strenuous strength workout can be a mental challenge, potentially enhancing mental resilience.
Conclusion

The placement of interval training in a strength workout largely depends on individual goals and preferences. Beginning with intervals can be ideal for those focused on enhancing cardiovascular fitness and burning fat. Placing intervals in the middle provides a balanced approach, giving equal weight to both strength and conditioning. Ending with intervals emphasizes strength training but adds a metabolic boost at the close. Recognizing the specific advantages of each setup allows individuals to adjust their training to best meet their goals.

CLIENT Spotlight -Jessie!
"Jessie and I started working together six months ago, almost to the day. She had been working out at home, and was looking to step up her strength training with some heavier weights. She also had been diagnosed previously with fibromyalgia, but had found that exercise helped decrease the symptoms.

Quickly she discovered how fulfilling it is to push herself with three of the big lifts: the squat, deadlift, and eventually the bench press. And with some - eh-hem - gentle prodding, she is also focusing on stability and balance to help aid in her overall training (she particularly “loves” single leg RDLs…ha)."
