How to Improve Vertical Jump Height Fast: A 4-Week IMU-Based Program for +5cm Gains
This 4-week, IMU-measured jump program combines CMJ, drop jumps, and deployment jumps for an average +5cm gain, tracked at 800Hz — no guesswork needed.
Why Form Breaks Down on Heavy Sets: 5 Reasons and a VBT Fix
Technique falling apart under heavy loads? Neural fatigue and core instability are usually to blame — here's the velocity-loss threshold that predicts it.
How Many Sets Per Week For Muscle Growth? Per-Muscle Volume Research
Beginner, intermediate, and advanced targets per muscle: chest 10-16 sets, back 12-22, quads 12-20 - plus the 7 variables that shift your number.
5x5 vs 3x10: Which Is Better For Strength and Hypertrophy?
5x5 vs 3x10 head-to-head: +12% vs +7% 1RM, +6% vs +8% muscle size in 12 weeks, plus a 3-day hybrid split with velocity-based load rules.
Polarized Training 80/20 Method: Scientific Distribution for Endurance
If easy days feel too hard and hard days too easy, moderate-intensity training may be the problem. Seiler's zone model plus an 8-week fix.
Altitude Training Mask Effectiveness: Does It Really Simulate Altitude?
Scientific analysis of altitude training masks vs real altitude hypoxia. What the research actually shows about VO2max, ventilatory drive, and hypoxic.
Submaximal Training Philosophy: Why 80% Beats 100%
Maxing out every session burns you out fast. Training at 80-85% consistently builds more strength over time, backed by CNS fatigue research.
Volleyball Libero Reaction and Dive Training: Defensive Specialist Fitness
Evidence-based reaction speed, lateral movement, and dive-recovery protocols for volleyball liberos. Includes norms, drills, and VBT monitoring.
Shoulder Rehab Training Guide: Return to Strength Roadmap
Most shoulder rehab plans stall between pain-free motion and full strength. This guide covers all four phases and real-time monitoring with PoinT GO.
How to Maximize Recovery Between Training Days
Your next session is only as good as your recovery window. Follow the sleep, nutrition, and active-recovery timeline elite programs use inside 48 hours.
Training Age Progression Roadmap: Beginner to Advanced
Not sure if you're a beginner or ready for advanced programming? This roadmap maps performance markers and VBT benchmarks to each training-age stage.
VBT vs Percentage-Based Training: Which Is More Effective?
Head-to-head research on velocity-based vs percentage-based loading — where VBT clearly outperforms on fatigue management, and where a hybrid wins.
