1. **State the problem:** The problem is to understand how to achieve the goal of doing 3 consecutive pull-ups despite lacking upper body strength. 2. **Relevant formula and explanation:** Pull-ups require upper body strength, particularly in the back, shoulders, and arms. To build this strength, training involves exercises that progressively overload these muscles. 3. **Step-by-step training plan:** 1. Train 3 times a week using a combination of assisted pull-ups (using bands or machines), negative pull-ups (slowly lowering from the top position), and resistance exercises like rows or push-ups. 2. Track your progress weekly by counting the number of reps you can do and gradually reduce the assistance as your strength improves. 3. Ensure adequate rest and recovery between sessions to avoid injury and maintain motivation. 4. If progress stalls, adjust your workouts by adding small variations or extra support exercises to target the muscles more effectively. 4. **Explanation:** This approach uses the principle of progressive overload, where muscles are gradually challenged more over time, leading to strength gains. Assisted and negative pull-ups help build the necessary muscles safely before performing full pull-ups. Final answer: Follow a structured training plan 3 times a week with assisted and negative pull-ups, track progress, rest adequately, and adjust exercises as needed to build upper body strength and achieve 3 consecutive pull-ups.
