Does this sound like the set of challenges you might be facing?
- My performance keeps sliding, my mood and sleep are tanking, and my gut reaction is to train harder to push through it
- My big event is a couple weeks out and every instinct screams to keep grinding right up to the day to stay sharp
- No single workout feels like too much, but the weeks keep stacking
- For a while I could add a little weight every single session and it felt amazing, but lately that exact same approach has dried up
- The same weights I’ve always handled fine are suddenly feeling brutal week after week, and I keep telling myself it’s just a bad day
Practices that may help
- Distinguish functional overreaching from non-functional overtraining
Functional overreaching (planned short-term overload) leads to supercompensation; non-functional overtraining is a breakdown that can take months to reverse.
Supercompensation - Taper before a target event to allow full supercompensation to express
Cutting training load 1–3 weeks before an event allows accumulated adaptations to fully express — this is not detraining.
Supercompensation - Track cumulative training stress, not just individual sessions
A single hard session is not the risk — it is the week-over-week accumulation of stress without matching recovery.
Supercompensation - Choose linear progression for beginners; switch to wave loading as you advance
Beginners can add load every session; intermediate and advanced athletes need weekly or monthly undulation to continue progressing.
Progressive Overload - Use post-session RPE review to detect overreaching early
Track the RPE drift across a training block — rising RPE at the same load is the earliest signal of overreaching.
The RPE Scale - Supercompensation
Supercompensation is the physiological principle that after a training stress and adequate recovery, the body adapts to a higher baseline than before — but only within a narrow timing window. Train again too early (still depleted) or too late (adaptation has faded) and the window is missed. The concept is foundational in periodization science; exact timing windows are individual and modality-dependent. - 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 - 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 - Deload proactively on a schedule — not reactively after injury or burnout
Scheduling deloads every 4–6 weeks prevents the fatigue accumulation that forces an unplanned break — which is always longer.
Deload Week - 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.

- Training Adaptation Peak
The highest adaptation occurs when the next stimulus lands during the supercompensation phase — above baseline recovery, before the adaptation fades.
Time your next training session to hit the supercompensation window
- Daily Undulating Periodization
Beginners can add load every session; intermediate and advanced athletes need weekly or monthly undulation to continue progressing.
Choose linear progression for beginners; switch to wave loading as you advance
- How To Avoid Overtraining
Reduce training sets by roughly half while maintaining the same load and rep ranges — this dissipates fatigue without losing neural drive.
Run a volume-reduction deload: cut sets by 40–60%, keep intensity
