Week 4 Highlights: OPEX Sustain
What We Covered This Week
Because the simplest aerobic work is often the most effective and the most demanding
How continuous MAP structures training from long to short
The progression from cyclical to mixed-cyclical to mixed sessions
Trust, buy, and how to stop projecting boredom to customers
Training elements that make aerobic work smooth, repetitive and sustainable
Why coaches should do the work themselves before prescribing it
A preview of next week’s focus on anaerobic training
The big change: Make aerobic training simple, measurable and rhythmic Trainers tend to overcomplicate aerobic work. This week made a key point: the simplest recipes, especially pure pacing cycle intervals, aren’t just effective, they’re tough. Sit on a bike and hold a pace for three to four minutes, rest, then repeat. No hiding and no transitions. It enforces rhythm and consistency, which is the heart of aerobic training.
A useful lens for coaches is to ask, can my client find and maintain a rhythm? If the answer is yes, the work is probably aerobic. If they have to stop, think or gas off, they probably aren’t. Create a sustainable rhythm first, then add variety later.
Within the MAP Continuum OPEX uses MAP, which stands for Maximum Aerobic Power, to organize aerobic training from long to short. Think of it as a gear system for stepping. It gives coaches a framework for time, rest, set, block and pace training areas.
Key ideas:
MAP ranges from 10 to 1, with MAP 10 being simple movement and MAP 1 being very short, hard aerobic intervals.
Structured progression runs from MAP 9 to MAP 1.
The training rate for each MAP is based on a simple rule of thumb: work time is multiplied by four. This guides how hard you should go during training without turning it into a test.
Example: If you train at MAP 9 for 30 minutes, your training pace is the 2-hour pace. This surprises people because it feels slow. Okay, that’s the point. Train on the right equipment for the right time zone.
MAP Cheatsheet for trainers
Level Map Standard Work Time Workout Pace Guideline Simple Example Map 9 30 minutes 4 times work time, so 2 hours pace 30 minutes easy set with repeat tempo MAP 5 4 minutes 16 minutes pace 4 minutes, 2 minutes easy, repeat MAP 3 1 minute 11 minutes, repeat MAP 3 1 minute 11 minutes, repeat seconds 2 minutes pace 30 seconds, 30 seconds of easy rowing
A full MAP 9 to MAP 1 progression in eight weeks per MAP is about 1.44 years. That kind of patience builds a real foundation and teaches clients their tools for life.
Sequence of Progress: Cycle First, Add Complexity Later Coaches often ask when to add fun or complex work. The advice this week was clear:
Start with circular work. Row, bike, ski, run. Learn gears here.
Move to a mixed circular. Combine cycle tools such as bike and skis or row plus VersaClimber.
Add final mixed work. Incorporate resistance patterns into aerobic sessions only when the client can keep the pace.
This series maintains a focus on pace and sustainability. It also reduces the risk of trying to make the native strong contractions aerobic before the client is ready.
Make it rhythmic or keep it out Aerobic training is all about finding a smooth rhythm and maintaining it. If a client can’t keep up with burpees, box jumps, and kettlebell swings without getting their heart rate up or breaking their form, pull those patterns out of aerobic sessions. Put them in resistance training. No drama, just clean lines between training types.
Customer buy-in: It’s about trust, not boredom A standout theme was buy-in. Trainers often fear that clients will tire of aerobic work. The reality he shared during office hours was the opposite. Most customers are not bored. Coaches get bored and project it on clients.
Two useful truths:
Clients trust simple plans when they trust the coach. If you get pushback, it can be a trust issue, especially at the beginning of the relationship. Clear consultations and personal sessions help build this trust quickly.
Results drive buy-in. When clients feel better, sleep better and make progress, they get excited about aerobic work.
Coach’s note: link aerobic work to what clients value. Connect their goals to the job. Want more energy for the kids, faster recovery between lifts, or better hiking? This bridge generates buy-in.
What the coaches are seeing this week
Dr. David Skolnick (DPT and strength coach) expected aerobic work to be his most difficult area. He is already testing and creating progressions using the MAP framework and seeing how clients handle 6 to 8 weeks of structured intervals.
Assistant instructor Melissa Gron echoed a common pattern: we overthink recipes. Keep it simple and customers will get the job done, feel great, and move on.
The Coaches Should Do the Work Theory alone is not enough. Space your writing and you’ll make better decisions. You’ll learn what the contractions feel like when they’re truly aerobic, where your stride falls apart, and which pairs are smooth. This can inform small but important calls like avoiding the row and heavy hip hinge plus burpee for someone who doesn’t have volume tolerance in hip flexion and extension.
Put a Year in Aerobic Training Try this as a professional experiment:
Commit to a structured MAP progression over a year. Keep it circular at first and then stir when ready.
Sprinkle in unstructured aerobic work as well. Walking, hiking, strolling. Notice how you feel, focus and recover.
Track simple metrics like pace repeatability, perceived effort and daily energy.
You will program with more confidence once you feel this works in your own system.
Why aerobic training is a foundation, not a phase This week started with a reminder that the aerobic system supports everything. You cannot perform at high outputs without a base. You also can’t recover well from strength work without it. Think about everyday life too. Walking hills, playing with the kids, hiking, long days on your feet, even clear thinking all benefit from a strong aerobic base.
Benefits worth noting:
Better recovery between hard sessions
Improved daily energy and mood
Support for cardiometabolic health and longevity linked to mitochondrial function
Cognitive clarity and focus from steady blood flow
Accessibility for every level, from 10-minute walks to long-distance sessions
Physical autonomy for life
Another piece that emerged during office hours: boredom is not the enemy. Being present and keeping a steady pace builds patience and resilience. This skill carries over everywhere.
How to start using MAP this week
Pick a MAP level and stick to it for a few weeks. Don’t jump around.
Keep it circular. Choose rower or bike.
Use the rhythm rule. Work time multiplied by four is your training pace.
Make it repeatable. The tempo in the set should match the tempo in the last set.
Train the rhythm. Smooth rhythm, soft grip, steady breathing.
Track results. Simple notes like “hold 220 watts at every interval” build confidence.
Want structured examples and complete progressions?
Coaches within CoachRx and LearnerX have access to a library of programs with MAP-based progressions. Browse, study intents and use them as inspiration for your customers. If you want the full training with context and practical application, explore the next group of coaching through the OPEX Method Level 1 (CCP Level 1) program page.
A Quick Example: Converting MAP into Practice Let’s say your client is newer to aerobic training and needs a simple start.
MAP Session 9: Easy 30 minute sequence at 2 hour pace. Focus on breathing through the nose, relaxed shoulders and smooth strokes.
MAP Session 5: 4 minutes, 2 minutes easy, 5 to 7 sets. Keep a repeat split that you could continue for 16 minutes if needed.
MAP Session 3: 1 minute activation, 1 minute easy, 10 to 12 sets. Keep every minute of work in a small separation range.
You can layer them throughout the week based on age and training goals. Always prioritize repeatability over chasing high performance.
What’s next: A Look at Anaerobic Work Next week he tackles ‘OPEX pain’ or anaerobic training. Expect a clear contrast between aerobic and glycolytic training because most general population clients do not require strenuous work and when sports or unique needs require it. Understanding the system helps you decide who should touch it and who shouldn’t.

Conclusion
The theme of the week was clear. Continue aerobic training simplerhythmic and repetitive. Use continuous MAP to set time, pace and progress. Build trust, train the pace and do the work yourself. When customers feel better and see progress, buy-in follows. Next, we’ll contrast aerobic versus anaerobic training so you can choose the right tool for each individual. Are you ready to train the basics to a higher level? Start by doing your own aerobic sessions this week.
