Strength Training Splits

splits.md

This 4-day rolling split is fully optimized (as of June 2026) to integrate running training with high-end hypertrophy and postural correction, balancing cumulative fatigue and protecting your lower back.

Same-Day Training Protocols (Iron Rules)

If a run and a gym session fall on the same day, adhere to these constraints:

1. The 6-Hour Rule: Maintain at least a 6-hour gap between sessions (e.g., Run AM, Gym PM) to allow CNS and glycogen partial recovery.
2. Back-to-Back Training: If forced to train consecutively, always Run first, Gym second. Never run immediately after heavy leg or compound lifting due to degraded running mechanics and elevated injury risk.

Routines

Day A: Frame | Heavy Push & Functional Running Core

• Same-Day Running Compatibility:
  • BEST MATCH: Easy Run (~10km Z2). Legs are fresh. Can be done back-to-back (Run first, then Gym).
  • AVOID: Long Run (~15+km Z2). High systemic fatigue destroys core stability needed for heavy pressing.
  • AVOID: Quality Run (Threshold/VO2max). Saps the CNS drive required for peak pressing power.
• Estimated Durations: 2 Sets: ~45 min | 3 Sets: ~65 min

Exercise	Primary Muscle	Secondary Muscle	Rest Time
Incline Bench Press (DB)	Upper Chest	Shoulders, Triceps	2–3 min
Seated Shoulder Press	Shoulders	Triceps	2–3 min
Triceps Dips (Weighted)	Triceps	Chest, Shoulders	2 min
Face Pulls (Cable)	Shoulder Rotators	Rear Delts, Upper Back	60–90 sec
Dumbbell External Rotation (L-Flys)	Rotator Cuff	Shoulder Stability	60–90 sec
Wrist Curls	Inner Forearm	Grip	30–60 sec
Wrist Twists	Forearm Rotation	Elbow Stability	30–60 sec
Pallof Press (Cable)	Deep Core / Obliques	Anti-Rotation (Run)	60 sec

Day B: Symmetry | Width, Thickness & Pure Pull

• Same-Day Running Compatibility:
  • GOOD MATCH: Quality Run. Great for high-intensity stacking (Run AM, Gym PM). Pull movements don't conflict with running mechanics.
  • GOOD MATCH: Easy Run. Safe with a 6-hour gap. If back-to-back, mind lower back fatigue during heavy T-Bar rows.
  • AVOID: Long Run. Spinal erectors will be too fatigued from running to stabilize heavy rows safely.
• Estimated Durations: 2 Sets: ~45 min | 3 Sets: ~65 min

Exercise	Primary Muscle	Secondary Muscle	Rest Time
T-Bar Row (Machine)	Mid-Back	Biceps, Rear Delts	2–3 min
Lat Pulldown (Cable)	Lats (Width)	Biceps	2 min
Pullover (Machine)	Lats / Chest	Serratus	90 sec
Reverse Fly (Single Arm)	Rear Shoulders	Upper Back	60–90 sec
Shrug (Dumbbell)	Upper Traps	Grip	60–90 sec
Seated Incline Curl (DB)	Biceps (Stretch Focus)	Forearms	60–90 sec
Preacher Curl (Machine)	Biceps (Peak Contract)	Forearms	60–90 sec
RKC Plank (Hardstyle)	Deep Core / Lower Abs	Glutes (Alignment)	45–60 sec

Day C: Anchor | Lower Body

• Same-Day Running Compatibility:
  • ELITE MATCH: Quality Run (Hard Days Hard). Only with a 6+ hour gap (Run AM, Gym PM) to bundle leg stress and preserve pure recovery days.
  • PROHIBITED: Long Run. Severe joint and tendon injury risk. Requires 24–48 hours of complete separation.
  • PROHIBITED: Easy Run. Interferes with leg hypertrophy signaling and will not feel "easy."
  • Note: Back-to-back training is strictly forbidden on this day.
• Estimated Durations: 2 Sets: ~55 min | 3 Sets: ~80 min

Exercise	Primary Muscle	Secondary Muscle	Rest Time
Leg Press	Quads	Glutes	3 min
Romanian Deadlift (BB)	Hamstrings	Glutes, Lower Back	3 min
Hip Thrusts	Glutes	Hamstrings	2–3 min
Leg Extension	Quads	None	60–90 sec
Leg Curls	Hamstrings	None	60–90 sec
Adductor	Inner Thigh	Groin	60 sec
Abductor	Outer Glutes	None	60 sec
Tibialis Raise	Shins	Ankle Stability	30–60 sec
Calves	Calves	Achilles Tendon	60–90 sec

Day D: Texture | Arm Priority & Sculpting Supersets

• Same-Day Running Compatibility:
  • BEST MATCH: Long Run (~15+km Z2). Perfect biomechanical split (Legs run, arms pump). Minimal CNS drain. Optimal: Run AM, Gym PM.
  • VERY GOOD: Easy Run. Low-energy pump session blends seamlessly with easy mileage.
  • AVOID: Quality Run. Isolation volume unnecessarily drains glycogen needed for hard threshold efforts.
• Estimated Durations: 2 Sets: ~40 min | 3 Sets: ~55 min

Exercise Block	Exercise	Primary Muscle	Rest Time
Warm-Up / Posture	Butterfly (Pec Deck)	Chest	60–90 sec
	Chest Crossover (Machine)	Lower Chest	60–90 sec
	Band Pull-Aparts	Upper Back / Rear Delts	60–90 sec
Superset A (Mass & Width)	A1. Triceps Extension (Cable)	Triceps (Long Head)	No Rest
	A2. Cross Body Hammer Curl	Brachialis / Outer Bicep	60–90 sec
Superset B (Isolation & Grip)	B1. Braced Single-Arm Cable Ext.	Triceps (Isolated)	No Rest
	B2. Reverse Wrist Curls	Outer Forearm	60–90 sec
Superset C (Shoulder Detail)	C1. Single Arm Lateral Raise	Mid Shoulders	No Rest
	C2. Chest Supported Y Raise	Rear/Mid Shoulders	60–90 sec
Core Finisher	Reverse Crunch	Lower Abs	60 sec
	Crunch	Upper Abs	Cold Finish

Extra Routine: Alignment | Pelvic Tilt & Posture

• Same-Day Running Compatibility:
  • BEST MATCH: Directly AFTER any run (Easy/Long/Quality). Acts as an ideal cooldown block to instantly release running-induced hip flexor tightness and realign the pelvis.
  • AVOID: Immediately BEFORE a Quality Run. Static stretching drops muscle tone and tendon elasticity, reducing power output for hard intervals.
• Purpose: Anti-Hollow-Back (Anterior Pelvic Tilt correction). Lengthens hyperactive hip flexors/quads and activates dormant glutes and core to re-align the pelvis for both heavy lifting stability and efficient running mechanics.
• Frequency: Perform on rest days, before runs, or as a dedicated mobility block.

Exercise	Target Group	Protocol	Focus Point
Lunge Stretch	Hip Flexors (Psoas)	2-3 Sets x 30 sec / side	Squeeze the glute of the back leg to deepen stretch.
Standing Quad Stretch	Rectus Femoris	2-3 Sets x 30 sec / side	Keep knees aligned; don't let the lower back arch.
Single Leg Laying Leg Raise	Deep Core / Lower Abs	2-3 Sets x 10-12 reps	Press lower back flat into the floor throughout.
Single Leg Glute Bridge	Glute Max / Pelvic Stability	2-3 Sets x 12-15 reps	Drive through the heel; keep hips perfectly level.

Extra Routine: Plyometrics

• Same-Day Running Compatibility:
  • BEST MATCH: Right BEFORE an Easy Run (~10km Z2). Acts as a neurological primer to increase tendon stiffness and elasticity while the ZNS is completely fresh.
  • STRICTLY PROHIBITED: AFTER long or intense runs. High injury risk; training elasticity on fatigued tendons causes acute joint and shin overload.
• Purpose: Running Performance & Elasticity. Builds Achilles tendon stiffness and improves running economy by training your nervous system to minimize ground contact time.
• Frequency: Best performed when completely fresh (e.g., before an easy run or on a dedicated dynamic day).

Exercise	Target System	Volume	Focus Point
Pogo Hops	Ankle Stiffness / Calves	3 Sets x 20-30 reps	Minimal ground contact time; land on the midfoot.
Box Jumps	Explosive Power / Extension	3 Sets x 5-8 reps	Land softly in a partial squat; step down safely.
Single Leg Box Jumps	Unilateral Power / Balance	3 Sets x 4-6 reps/side	Focus on knee alignment upon landing.
Single Leg Box Step Up	Concentric Strength / Drive	3 Sets x 8-10 reps/side	Explode upward using the top leg only; control down.

Miscellaneous

Key Takeaways for your 10-Day Cycle

• The Cramp Prevention Strategy: Biceps training is strictly limited to Day B and Day D. Do not add casual bicep movements on Day A or C. If neural tightness occurs post-workout, utilize Median Nerve Flossing and active Reciprocal Inhibition (fully flexing the triceps to force the biceps to release).
• Plateau Breaking (Reverse Pyramid): On heavy compound lifts (especially Incline Press), starting with your heaviest load and dropping weight on subsequent sets (e.g., 8x44kg -> 8x40kg -> 8x36kg) is highly encouraged to maintain perfect technical and postural execution under fatigue.
• The "Gap": Since this is a rolling cycle, if your legs feel exceptionally heavy after Day 3, insert an extra rest day (utilizing the Alignment routine) before starting Day 1 again.

Rest times

Exercise Category	Rest Time	Why?
Primary Compounds (Incline Press, T-Bar Row, Leg Press, RDL)	2 – 3 Minutes	These require high neurological output. To lift heavy loads safely and preserve running economy, your ATP stores need time to reset completely.
Secondary Isolations & Supersets (Face Pulls, Day D Blocks)	60 – 90 Seconds	Shorter rest increases metabolic stress, which is the primary driver for the muscle "pump", posture correction, and hyper-efficient time-saving.
Detail & Prehab (Forearms, Core, Tibialis, Alignment)	30 – 60 Seconds	These are smaller muscle groups or stability drills that recover very quickly. Keeping the rest short keeps the focus on precise motor control.
