Private coaching — application only.

The problem

Your hamstring already knows the pop. One more sprint, one more kick — and you're out for months. Again.

No bands. No assisted descents. No fake full range. You officially advance only when you pass the benchmark for your active phase — not when another week passes. Every time you push pace without eccentric capacity, you're stacking debt your hamstrings will collect at the worst possible moment.

// Outcome

What you'll build.

Develop complete Nordic capacity through seven benchmark-gated phases: foundation and patterning, range acquisition, strength development, eccentric ownership, eccentric overload, concentric ownership, and full Nordic mastery. Full system access from Day 1 — one active training phase; progression earned through performance.

Carries over to sport

Sprint acceleration, kick deceleration, and change of direction — the moments hamstrings actually tear.

Full system access

FULL SYSTEM ACCESS FROM DAY 1. BENCHMARK-GATED PROGRESSION THROUGHOUT.

Explore the complete Nordic Hamstring Mastery system immediately after enrolment. Every phase, exercise demonstration and performance standard is available so you can understand the entire progression from the beginning.

Content access is immediate. Training progression is earned through benchmarks — not founder approval and not the calendar.

How progression works

  1. 1Explore the complete system from Day 1.
  2. 2Begin training in your assigned Active Phase.
  3. 3Complete the minimum required phase exposure.
  4. 4Pass the phase benchmark using the Dark Kinetics Rep Standard.
  5. 5Mark the phase complete and activate the next training phase.

The week numbers describe the expected route. They do not automatically unlock training progression. Complete the required exposure. Pass the benchmark. Earn the next Active Phase.

7 phases · one active training phase

All standard education is visible from enrolment. Future phases remain available as previews — do not begin the next prescription until the current benchmark has been passed.

  1. Phase 1 · Foundation & Patterning · Active phase when you begin

    Active phase

    Learn rigid shoulder–hip–knee alignment, hamstring tension, and high-box eccentric control. Establish the movement pattern before range expands. No bands, no hand assistance on working reps. Phase 1 is typically completed around Week 1.

  2. P2

    Phase 2 · Range Acquisition · Preview available

    Preview available — do not begin until previous benchmark passed

    Progressively lower box targets — high to medium to low — earning greater eccentric range through structured, controlled descents. Every centimetre earned through hamstring strength and technical ownership. Phase 2 is typically reached around Week 2.

  3. P3

    Phase 3 · Strength Development · Preview available

    Preview available — do not begin until previous benchmark passed

    Deepen eccentric strength and tissue tolerance through accumulated range work. Build the foundation required before full floor ownership and overload benchmarks. Phase 3 is typically reached around Week 3.

  4. P4

    Phase 4 · Eccentric Ownership · Preview available

    Preview available — do not begin until previous benchmark passed

    Benchmark to pass: 3×6 controlled eccentric Nordic reps · minimum 4-second eccentric on every rep · straight shoulder–hip–knee alignment · no hip break · controlled contact with the floor/target. Phase 4 is typically reached around Week 4 or later. Official progression advances only after this benchmark passes.

  5. P5

    Phase 5 · Eccentric Overload · Preview available

    Preview available — do not begin until previous benchmark passed

    Benchmark to pass: 2.5 kg external load · 3×4 controlled eccentric reps · minimum 3-second eccentric on every rep · perfect body alignment maintained. Phase 5 is typically reached around Week 5 or later. Official progression advances only after this benchmark passes.

  6. P6

    Phase 6 · Concentric Ownership · Preview available

    Preview available — do not begin until previous benchmark passed

    Benchmark to pass: 3×6 clean concentric Nordic reps · no push-off from the floor · full body alignment maintained · smooth controlled concentric execution. Phase 6 commonly spans Weeks 6–8 or longer. Official progression advances only after this benchmark passes.

  7. P7

    Phase 7 · Full Nordic Mastery · Preview available

    Preview available — do not begin until previous benchmark passed

    Performance standard: 3×6 perfect full Nordic reps · minimum 4-second eccentric on every rep · reach the floor under complete control · hold a 3-second glute squeeze at the bottom · return concentrically without assistance · no hip break · perfect shoulder–hip–knee alignment. Phase 7 commonly spans Weeks 9–10 or longer.

How Progression Works

1. Explore the complete system from Day 1. 2. Begin training in your assigned Active Phase. 3. Complete the minimum required phase exposure. 4. Pass the phase benchmark using the Dark Kinetics Rep Standard. 5. Mark the phase complete and activate the next training phase. You are never forced to train blind. You can study the full pathway from the beginning, understand what comes next and prepare intelligently. But viewing the next level is not the same as earning it. The week numbers describe the expected route. They do not automatically advance your Active Phase. Time alone never advances training progression. Complete the required exposure, pass the benchmark, and earn the next Active Phase.

Benchmark-Gated Progression

Dark Kinetics is built on objective performance standards — not calendar weeks. Athletes never officially advance simply because another week has passed. Every phase has a measurable benchmark. If the benchmark is not achieved, the athlete remains in the current Active Phase until it is successfully passed. All standard educational content is visible from enrolment; only official training progression and phase completion require benchmark proof. Phases 1–3 establish foundation, range, and strength. Phases 4–6 earn eccentric ownership, eccentric overload, and concentric ownership. Phase 7 is the Gate performance standard.

Why Dark Kinetics Does Not Use Band Assistance

Some coaches successfully use resistance bands during Nordic progressions — and that approach has helped many athletes build hamstring capacity. Dark Kinetics deliberately chooses a different methodology. We do not use resistance-band assistance during Nordic progressions. We also avoid using the hands for assistance unless absolutely necessary for safety reasons. Instead, athletes progressively earn greater unsupported range through structured, benchmark-based progressions — high-box to medium-box to low-box eccentrics, then full floor ownership, then controlled overload. Every centimetre of the movement is earned through hamstring strength, control, and technical ownership. That is the Dark Kinetics standard.

Phase 7 · Full Nordic Mastery

This is the final phase of Nordic Hamstring Mastery. Performance Standard To achieve the performance standard in Nordic Hamstring Mastery, the athlete must demonstrate: • 3 × 6 perfect full Nordic Hamstring Curls • Minimum 4-second eccentric on every repetition • Reach the floor completely under control • Hold a 3-second glute squeeze at the bottom • Powerful concentric return without assistance • No hip break • Perfect shoulder–hip–knee alignment • Every repetition performed according to the Dark Kinetics Rep Standard Completing this benchmark records Gate standard achievement for the athlete from Nordic Hamstring Mastery. You did not simply complete a program. You earned every centimetre of the movement through measurable performance standards. Every repetition had to meet the Dark Kinetics Rep Standard. You leave the system with complete ownership of one of the world's most demanding bodyweight strength exercises.

Beyond the Performance Standard

Achieving the performance standard in Nordic Hamstring Mastery unlocks access to the hidden Dark Kinetics Nordic Standard. This advanced optional elite system remains completely inaccessible until the athlete successfully passes Phase 7 — Full Nordic Mastery. The movement, standards, and progression are intentionally withheld until the performance standard is achieved. Not every athlete reaches this level.

The Dark Kinetics Rep Standard

Rigid shoulders-to-knees line · full hip extension · glutes engaged · zero intentional hip hinge · no collapse · no bounce · no momentum · no assistance during the working repetition. Hands may reset kneeling only after contacting the box or floor — not as part of the rep.

Platform Delivery

The platform shows your active phase, prescribed sessions, current benchmark, minimum exposure, benchmark status, and next phase. All standard demonstrations and phase overviews are available from Day 1. Active Phase advancement is earned through logged benchmark performance — not calendar completion.

Equipment & Safety

Secure Nordic station or safe ankle anchor · thick knee padding · stable high, medium, and low box targets · 2.5 kg plate for Phase 5 · optional sliders and accessory equipment. All box targets must be stable, load-bearing, appropriately padded, and positioned so they cannot slide during the descent.

Seven benchmark-gated phases with one active training phase at a time. All standard content visible from enrolment; official progression earned through logged performance — not calendar completion.

// Platform Delivery

Delivered on the Dark Kinetics platform.

Content access is immediate. Training progression is earned. After enrolment you can view all seven phase overviews, the complete exercise library, every benchmark, and the expected ten-week pathway. One phase is your Active Phase at a time — future phases remain visible as previews labelled Preview Available. Official advancement requires minimum phase exposure, passing the phase benchmark under the Dark Kinetics Rep Standard, and logging your result in the platform. Time alone never unlocks the next training phase. Passing the Phase 7 performance standard unlocks the hidden Dark Kinetics Nordic Standard — the only optional elite instructional content withheld until mastery is proven.

Who it's for

Athletes, lifters, footballers, sprinters, jumpers, combat athletes, and serious trainees who want measurable Nordic strength rather than random hamstring exercises.

Who it's not for

Anyone looking for instant progression, assisted repetitions being counted as mastery, or advancement based only on the calendar.

Need the engineer rebuilding every variable weekly — not just checkpoint review on a fixed system? Private coaching is application-only at /coaching.
