Coaching practices for Every Workout I Do is Moderately Hard and Leaves Me a Bit Wrecked and My Fitness Has Plateaued I Keep Hearing I'm Supposed to Do a Lot of Genuinely Easy Aerobic Work to Build a Base but Going That Slow Feels Like it Can't Possibly Be Doing Anything
Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Every Workout I Do is Moderately Hard and Leaves Me a Bit Wrecked and My Fitness Has Plateaued I Keep Hearing I'm Supposed to Do a Lot of Genuinely Easy Aerobic Work to Build a Base but Going That Slow Feels Like it Can't Possibly Be Doing Anything, these are the strongest matches in the current practice library.
Does this sound like the set of challenges you might be facing?
- Every workout I do is moderately hard and leaves me a bit wrecked, and my fitness has plateaued
- Every workout I do lands in the same moderately-hard middle gear
- I think my easy runs are supposed to feel easy, but I always seem to drift into puffing too hard to talk
- Every time I start getting in shape I go too hard in the first week, end up wrecked and sore and demoralized, and quit by week two
- Every workout I push until I’m gasping because that feels like the only thing that counts, and I’m starting to wonder if I’m skipping the slow, easy hours that actually build the engine I keep trying to redline.
Practices that may help
- Zone 2 training to build aerobic base
Low-intensity, sustainable aerobic exercise performed 3–4 hours per week develops mitochondrial density — the foundation of a high VO2 max.
VO2 Max and Longevity: Training Your Aerobic Ceiling - Pair zone 2 with occasional high-intensity work in an 80/20 polarized structure
Most training volume in zone 2, a small fraction at near-maximal intensity — skip the moderate middle.
Zone 2 Training - Train at conversational pace for aerobic base
Keep effort low enough to speak in full sentences — the sweet spot for building aerobic capacity.
The Talk Test: Gauge Exercise Intensity Without a Monitor - Use conversational pace to build exercise tolerance safely
New exercisers who train entirely within conversational pace build fitness while avoiding the discouragement of early burnout.
The Talk Test: Gauge Exercise Intensity Without a Monitor - Build a zone 2 aerobic base
Log 3–4 hours per week of low-intensity aerobic exercise to develop mitochondrial density and fat-oxidation capacity.
VO2 Max and Longevity: The Peter Attia Framework - Build aerobic base with easy running to raise the VO2max ceiling over time
High-intensity intervals raise VO2max faster in the short term; aerobic base training raises the long-run ceiling.
VO2max Training - Autoregulate daily training load using RPE
If a planned moderate session feels like an 8/10 instead of the usual 6/10, your body is telling you something — adjust the session accordingly.
The RPE Scale - Polarized training distribution for sustainable VO2 max gains
Spend 80 % of training time in Zone 2 and 20 % in Zone 4–5 — the combination elite endurance athletes and longevity-focused medicine both support.
VO2 Max and Longevity: Training Your Aerobic Ceiling - Find your personal zone 2 intensity by the talk test
Zone 2 is the highest pace at which you can speak in full sentences without audible breathlessness.
Zone 2 Training - VO2 max intervals (Zone 4–5) to push your aerobic ceiling
Four-minute intervals at near-maximal effort, repeated 4–6 times, are the most efficient way to raise your VO2 max.

- When Rucking Rucking Cardiovascular Zone
Rucking at moderate pace with 15–20% body weight achieves zone 2 heart rate for many people who cannot reach it with unloaded walking.

- Best Zone 2 Exercise
Zone 2 is low-intensity aerobic exercise — roughly the hardest pace at which you can hold a full conversation — that specifically trains mitochondrial density, fat oxidation, and metabolic flexibility. The metabolic mechanisms are well established in exercise physiology; translating this into longevity outcomes is compelling but largely observational.
