Coaching practices for Sub Maximal Effort
Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Sub Maximal Effort, these are the strongest matches in the current practice library.
Does this sound like the set of challenges you might be facing?
- Every time I train I push each set until my arms are shaking and I have to take three days off to recover
- I’ve been logging plenty of easy miles and my aerobic base feels solid, but the top-end number won’t climb
- I’ve been lifting for years and the weight I can press feels almost easy on the way down
- I’ve had a steady base for a while but my hardest ceiling hasn’t budged in months, and I think I’ve been too comfortable
- Every workout I do lands in the same moderately-hard middle gear
Practices that may help
- Train at 40-60% of maximum — the sub-maximal effort rule
Each GTG set should feel easy: you stop well before any form breakdown or perceived effort.
Greasing the Groove, Made Practical - 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.
VO2 Max and Longevity: Training Your Aerobic Ceiling - Eccentric overload using bands or weight releasers
Load the lowering phase heavier than the lift to force genuine eccentric overload.
Eccentric Training, Made Practical - VO2 max intervals
Use 4–8 minute high-intensity intervals at near-maximum effort to directly stress and expand your oxygen ceiling.
VO2 Max and Longevity: The Peter Attia Framework - 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 - 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 - Use the broken-speech threshold for hard intervals
When you can only get out single words, you are in the high-intensity zone — useful for timing interval work.
The Talk Test: Gauge Exercise Intensity Without a Monitor - Train at vVO2max with 3–5 minute intervals to accumulate maximum time at VO2max
The greatest VO2max stimulus comes from spending as many minutes as possible near your maximum aerobic power — intervals at vVO2max do exactly that.
VO2max Training - Understand that effort — not duration — is the active ingredient
A 7-minute workout at 50% effort produces little; the same 7 minutes at 90% effort produces a real training stimulus.
The 7-Minute Workout, Made Practical - Treat anything beyond the minimum as a bonus
Complete the minimum first, then let further effort be strictly optional — never obligatory.
