DID YOU KNOW❓

Stopping your training while in-season can result in measurable losses in strength, speed, and power during the most important time of year...PLAYOFFS.

The Timeline of Strength and Power Loss as reported by various sports and medical research studies:

👉 Weeks 1 to 2: Maximal strength stays mostly stable. The nervous system and muscles rely on previous training adaptations.

👉 Weeks 3 to 4: Minor drops in explosive power begin. Fast-twitch muscle fibers start losing recruitment efficiency.

👉 Weeks 5 to 8: Explosive output and speed decay by 15% to 25% from peak levels.

👉 Weeks 8 to 12: Maximal force production drops by 7% to 12% due to reduced muscle fiber size and lower nerve activation.

There's a reason college and professional athletes train year-round. Don't look back on your last 3-4 months of hard work and neglect the importance of in-season maintenance training.
