To decide which physical activities incorporate strength on a regular basis, we need to consider activities that involve resistance training or bodyweight exercises. Here are some options:

1. Weightlifting: This activity typically involves lifting weights or using resistance machines to challenge and strengthen different muscle groups.

2. Calisthenics: Bodyweight exercises like push-ups, squats, lunges, and planks are great for building strength as they rely on your body's weight as resistance.

3. Yoga: While yoga is primarily known for its flexibility and balance benefits, it can also help improve strength through poses like downward dog, plank, and warrior poses.

4. CrossFit: CrossFit workouts generally involve a combination of functional movements, weightlifting, and high-intensity interval training (HIIT), making it a suitable option for incorporating strength training.

5. Circuit training: This type of workout involves moving through a series of different exercises targeting different muscle groups, usually with minimal rest in between. It can be done with bodyweight exercises or by incorporating resistance bands or weights.

6. Pilates: Pilates focuses on improving core strength, stability, and muscle control. It often involves exercises using specialized equipment or mat-based exercises that target different muscle groups.

7. Martial arts: Many martial arts disciplines, such as judo, taekwondo, and Brazilian jiu-jitsu, require significant strength and conditioning training to support the execution of techniques and movements.

Remember, it's essential to consult with a fitness professional or medical expert before incorporating any new physical activities into your routine, particularly if you have any pre-existing health conditions or concerns.
