If You’re Not Sprinting Faster, This Is Why.

Key idea: your “weak link” limits your speed

Speed and explosiveness progress are capped by the weakest link, which is a mix of:

• Physical qualities
• Technical qualities
• Genetics

The 5 most common weak links (and how to identify/fix them)

1) Reactive strength / stiffness / elastic power

Why it matters How well you transition from eccentric → concentric (stretch-shortening cycle).

Common signs

• Longer gun contact times (e.g., >0.25 s)
• Slower max velocity time (e.g., >1.35 s, as mentioned)
• Shin splints from sprinting/plyos (often indicates poor elastic energy storage/release)

Fixes / strategies

• Ankle-dominant plyometrics with fast ground contacts
  • e.g., bounds, pogo hops
• Build relative + isometric calf strength
  • calf raise holds, calf raise pushes, single-leg calf raises
• Improve foot/arch mechanics (examples)
  • barefoot sprints, barefoot technique drills
  • seated calf raise, towel crunches
• Use a focused plan if needed
  • e.g., a “free 14-day speed program” for ankle stiffness

2) Rate of force development (RFD)

Why it matters How quickly you can produce force—“explosiveness speed,” not just strength.

Common signs

• Strong in the weight room but still not fast
  • examples given: <4.8 s 40-yard or <11.4 s 100m (thresholds mentioned)
• You mostly lift and do less sprint-focused work
• Performance drops when time is limited (fast-window tasks)
• Example comparison test described:
  • if static jump ≈ counter-movement jump (or poor drop-jump performance), you likely aren’t using the stretch-shortening cycle effectively

Fixes / strategies

• Ballistic strength (move objects fast)
  • med ball throws
  • Olympic variations (example mentioned: high pull)
• Plyometrics for speed/height/distance with max intent
  • track jumps + contact times; effort/intention matters
• Resisted sprints (extend training stimulus for peak power)
  • because peak power drops after ~5–10 yards, resistive work helps maintain a better force/power stimulus

3) Neuromuscular coordination

Why it matters Coordination between your nervous system + muscles. Includes:

• Intra-muscular coordination (within muscle)
• Inter-muscular coordination (between muscles)

It shows up as poor sprint mechanics because it can’t be “willed” into place—it’s trainable.

Common technical errors called out

• Overstriding
• Knee extension before hip extension
• High heel recovery / acceleration mechanics issues
• Torso position errors (too far forward or too upright in upright sprinting)
• Pelvic tilt problems (anterior or posterior tilt issues mentioned)

Fixes / strategies

• Prefer structural drills (not just random social media “A-series” drills)
• Train co-contraction (fire one group while relaxing the other)
  • examples: oscillation-based training (oscillation hops/lifts) and plyometric drills
• Use high-speed technical drills
  • straight-leg bounce → strides
  • flex-leg bounce → strides
  • mini-hurdle sprints
• Add resisted sprints and resisted versions of technique work
• Focus on posture + foot contact relative to center of mass
  • avoid overstriding; don’t “drive the foot down and back” excessively

4) Durability / consistency (staying healthy, training for months)

Why it matters You can’t improve long-term if injuries interrupt training.

Fixes / strategies

• Isometric strength at hip/knee/ankle
• Gradual loading of weekly volume
  • rule of thumb: don’t spike above ~20% weekly workload
• Clear daily goals
  • example: 2 max-sprint sessions/week (often Mon + Fri)
• Mobility + technical efficiency work across training (sprints + lifts + plyos)
• Match plyometric difficulty to readiness
  • pick the right level (example progression: level 1 basic jumps → level 4 fast round contacts like hurdle hops)
• Outside training consistency plan
  • nutrition (high carbs + protein mentioned)
  • sleep (target 7–9+ hours mentioned)
  • consistent training plan (example: Speed Academy)

5) Training periodization / planning

Why it matters Structured planning prevents injuries and improves performance despite high training stress.

Common periodization/programming problems

• No structure (“going with the flow”)
• Feeling overtrained (mental fatigue, joint pain, frequent illnesses, losing motivation)
• Training constantly but going backwards

Fixes / strategies

• Use a high-low training model (example given)
  • hard sprint/jump/heavy lift days: Mon/Wed/Fri
  • lighter days: mobility + upper body + active recovery (Tue/Thu/Sat or similar)
• Use a cutback / deload to trigger supercompensation
  • after enough volume, reduce workload for about 1–2 weeks
  • aim to beat the PR at the start of the training phase
• Ensure volume and intensity are in the right range
  • too much volume prevents supercompensation and leads to fatigue/survival mode
• Manage recovery basics
  • sleep + nutrition + overall workload control
• If you’ve trained hard and still aren’t improving
  • the issue is likely recovery and periodization, not effort

---

Productivity / action guidance implied by the program structure

• Use a consistent training framework rather than random training:
  • Max sprint sessions (2x/week example)
  • high-low weekly split
  • planned deloads (1–2 weeks)
• Troubleshoot systematically:
  • identify which of the 5 weak links matches your symptoms
  • then apply the specific fixes tied to that weak link
