All protocols

Do not rely solely on low-intensity physical activity without structured exercise.

One way to increase physical activity is to do a 10-minute walk three times per day.

A sample four-day split: day 1 strength in the 5–10 rep range; day 2 long-duration work; day 3 11–30 rep muscular endurance/bodyweight/yoga/Pilates/gymnastics/group class/circuit work; day 4 medium-intensity conditioning plus a short max-heart-rate finisher. Favor mostly whole-body, multi-joint exercises. Place long-duration work after strength because it can be restorative when the whole body is sore.

A group activity class can fit well on the muscular-endurance day; examples given include spin class or dance class. If a dance class mainly trains the legs, finish with about 10 minutes of upper-body light weights, such as sets of 30 reps, to balance the body.

For the fourth day, use medium-intensity conditioning with alternating harder and easier periods rather than all-out work; a sample protocol is one minute on, one minute off on the bike, with the hard minute at about 85–90% heart rate and the easy minute around 50%.

A favored protocol on the Assault Bike: do a solid 10-minute warmup, recover, then go five minutes and cover as much distance as possible, followed by about 10 minutes of gradual cooldown. During the last ~2 minutes of cooldown, use deliberate 5-second nasal inhales and 5-second nasal exhales.

If you did not sleep well or do not feel recovered, slide the workout forward by a day rather than forcing it.

If very sore, use low-intensity cardio such as jogging, biking, skipping rope, and walking to help dissipate soreness.

To create a six-day program, run the three-day split back-to-back and take one day off.

If you modify the plan, make it a deliberate program change rather than changing things ad hoc every day.

Balance listening to your body with honest self-assessment so you do not confuse true recovery needs with laziness.

When training with others, invite them into your plan rather than abandoning your plan to follow theirs.

When traveling, use simple hotel-gym workouts to get movement in and help with jet lag; one sample workout is one set of 10–15 reps on every machine in the order they are laid out.

Occasionally do fun off-program training with others if the recovery cost is no more than about three days; downregulate your effort if needed to keep the cost manageable.

Use breathing techniques and patterns as a first lever to improve endurance; improve your breathing pattern and overall approach, avoid over-breathing early, and use more strategic breathing to prevent later problems.

Maintain proper posture and positions during endurance training; avoid being hunched over, especially on a bike.

Refine movement technique to improve efficiency, since efficiency trumps force for endurance.

Train across the full endurance spectrum rather than choosing only steady-state or only HIIT.

For fat loss, pick any training tactic you can maintain consistently over time; adherence matters more than modality. Choose something challenging that you somewhat enjoy or can at least tolerate, and avoid modalities you hate.

Use endurance training to bring resting heart rate down; the target suggested is sub-60 bpm or close, with over 70 bpm viewed as a sign of poor fitness unless something else is going on.

Include training that gets you up toward maximum heart rate; this should not be avoided.

Perform a standard workout fasted and compare performance, heart rate, perceived exertion, and heart-rate recovery; little drop in performance and normal recovery suggest decent fat utilization, while prolonged recovery may indicate poor fat utilization.

Consume about 50 g of carbohydrate and observe whether you crash about 30 minutes later; a crash suggests poor carbohydrate utilization.

Higher-carbohydrate meals later in the day are described as useful, including for athletes cutting weight or trying to reduce weight; the idea that late carbs inherently increase fat gain is rejected.

Eating fat before a workout biases the body toward using more fat as fuel and can be used to train fat utilization; caveat: this does not necessarily increase fat loss and may reduce peak performance.

Consuming carbohydrate before or right before exercise biases the body toward using carbohydrate as fuel and can help train carbohydrate utilization, especially with higher-intensity training.

Keeping total caloric intake managed is presented as a major practical step for improving fuel use and body composition.

Use appropriate food combinations, especially pairing carbohydrates with fiber and/or protein, to blunt the rise in blood glucose, reduce post-carbohydrate bonking, and improve energy management through the day.

For better energy management throughout the day, keep protein intake stabilized.

To get better at using carbohydrates as fuel, train at higher intensity.
