Final answer:
The 4 fundamental principles that determine the effectiveness of resistance training programs are progressive overload, specificity, recovery, and variety.
Step-by-step explanation:
The 4 fundamental principles that determine the effectiveness of all resistance training programs are:
- Progressive overload: To continuously see progress, you need to gradually increase the intensity, such as the weight or reps, as your muscles adapt to the current workload.
- Specificity: Training should be specific to the goals you want to achieve. For example, if you want to improve strength, focus on exercises that target the major muscle groups.
- Recovery: Muscles need time to repair and grow stronger after each workout. Adequate rest and recovery are crucial for optimal results.
- Variety: Changing your exercises and routines periodically can prevent plateaus and keep your workouts interesting and effective.
