Progressive Overload; What the Latest Research Really Says
Progressive overload isn’t just “add weight every week.” It’s the systematic increase of training stress across multiple levers—load, reps, sets (weekly volume), range of motion, frequency, and even targeted fatigue—so tissues keep adapting without tipping into non-functional fatigue.1) You can “overload” by load or reps—and both work A controlled trial comparing two strategies—adding load vs. adding reps on leg extensions—found similar increases in 1RM strength and muscle size after 10 weeks. Translation: if bar speed or recovery limits heavier loading, progressing reps at a given load can still drive gains.2) Volume is powerful, but has diminishing returns Meta-analytic modelling shows a clear dose–response between weekly training volume and hypertrophy and strength, but with diminishing returns at higher volumes (i.e., more isn’t endlessly better). Use volume as a primary overload lever, then taper increases once progress slows.3) Velocity loss as a smart fatigue “dial” In velocity-based training, the velocity-loss (VL) threshold within a set acts like a fatigue governor. Higher VLs (e.g., 20–40% drop in rep speed) tend to produce more hypertrophy but accumulate more fatigue, while lower VLs preserve readiness and strength expression. Choose VL to match the phase: higher for growth blocks, lower for strength/peaking.4) Autoregulation helps match today’s capacity—just don’t expect magic RPE/RIR or APRE can effectively align daily stress with readiness, but recent work suggests no consistent advantage over well-designed fixed-load prescriptions when intensity/volume are equated. Use autoregulation to avoid bad days becoming bad blocks, not as a guaranteed accelerator.5) Deloads: useful tool, not a law of nature A recent supervised study found a one-week mid-block deload minimally affected hypertrophy and may reduce strength versus continuous training. Practical read: schedule deloads based on performance and readiness trends (e.g., HRV, bar speed, reps at a target load), not the calendar alone. 6) ROM and long-length work are underrated overload vectors Expanding range of motion, especially emphasizing long muscle lengths, can meaningfully raise mechanical tension and growth stimulus—another way to overload without chasing heavier loads every session.7)Power, Acceleration, & RFD- use Velocity at Percentage of Bodyweight or Load at Specific Velocities. Consider looking at time to Peak Velocity.Putting it together: a modern overload playbookPick 1–2 primary levers per block. • Hypertrophy block: progress weekly sets and/or reps, use VL 20–30%, and widen ROM.• Strength block: progress load week to week, keep VL 10–15%, and hold volume steady.Track two simple KPIs:• Reps @ 75–80% 1RM (or weight at a fixed RPE/RIR)• Best rep velocity on your main lift warm-upsIf both stall for 2–3 exposures, add a small dose of volume (e.g., +2–4 weekly sets for that muscle) or reduce VL/fatigue and push load.Autoregulate with guardrails:• Target 1–3 RIR on most working sets.• If warm-up bar speed is ↓ and RIR feels tighter, keep load but shave a set (maintain quality).• If bar speed is ↑ and RIR feels easier, add a small top-set or back-off set.Deload only when the data say so:• Use a low-VL week and cut volume by ~30–40% when readiness, bar speed, and pump/DOMS pattern indicate accumulating fatigue—not simply because “week 4.”This is what we use at www.RiseIndoorSports.com.https://www.mashelite.com/product-category/gymaware/ for your Velocity needs.New EBook "Mash Explosion" https://www.mashelite.com/product/mash-explosion-power-training-plyometrics/"Mash Explosion" EBook and New Program at: https://www.bridgeathletic.com/product/mashexplosionebookandprogramforimprovedjumpssprintaccelerationathleticpower-1633531
