wunder beta🏋️ Strength Training 101
Build muscle and strength with the science of resistance training.
What you’ll learn
- Explain how muscles grow and the mechanisms that drive hypertrophy.Hypertrophy occurs when muscle protein synthesis exceeds breakdown, driven mainly by mechanical tension alongside muscle damage and metabolic stress, with sufficient load recruiting more fibers.
- Apply progressive overload and training variables like volume and frequency.Progressive overload plus enough weekly volume, spread across training each muscle 2-3 times per week with appropriate sets and reps, drives continued strength and muscle gains.
- Use protein, recovery, and consistency to turn training into results and lasting health.Adequate protein (1.5-2 g/kg), proper recovery and sleep, and long-term consistency complete the muscle-building process and deliver broad benefits for metabolism, function, and healthy aging.
Questions this course answers
When does muscle hypertrophy occur?
Hypertrophy occurs when muscle protein synthesis exceeds muscle protein breakdown over time, tipping the balance toward building.
Which of the three drivers of hypertrophy is considered most essential?
Mechanical tension, the force muscles produce to overcome resistance, is considered the most essential driver of muscle growth.
Why does training intensity matter for recruiting muscle fibers?
Challenging loads ensure maximal muscle fiber recruitment, activating the larger high-threshold fibers needed for full hypertrophy.
What is progressive overload?
Progressive overload means gradually increasing the demands placed on muscles so they keep adapting and growing.
How often should each major muscle group be trained for best results?
Training each major muscle group two to three times per week is superior to once-weekly training, since protein synthesis returns to baseline within about 36 to 48 hours.
Why is total weekly training volume important?
Total training volume, the amount of challenging work per muscle across the week, is a major driver of hypertrophy, which is why frequency helps.
