why should you change your workout 4-6 weeks? what types of changes can be made?

It is beneficial to change your workout every 4-6 weeks to prevent plateaus and continue seeing progress. When you do the same workout routine for an extended period of time, your body adapts and becomes more efficient at performing those exercises, leading to diminished results.

Some changes that can be made to your workout routine include:

1. Increasing the intensity: This can be done by adding more weight, increasing the number of repetitions or sets, or decreasing rest time between exercises.

2. Changing the exercises: Switching up the exercises you do can target different muscle groups and prevent overuse injuries.

3. Varying the rep ranges: Altering the rep ranges (low reps for strength, high reps for endurance) can challenge your muscles in different ways.

4. Incorporating new equipment: Trying out new equipment or workout techniques can keep your routine interesting and engage different muscle groups.

5. Modifying the workout split: Changing the frequency and distribution of muscle groups worked in each workout can provide a new stimulus for muscle growth.

Overall, changing your workout routine every 4-6 weeks can help prevent boredom, challenge your body in new ways, and maximize your fitness gains.
