Which training intervention is recommended for low strength levels in the upper body?

Resistance training is the recommended intervention for addressing low strength levels in the upper body. This type of training specifically focuses on strengthening muscles through the use of weights or resistance. It is effective because it promotes muscle hypertrophy, enhances neuromuscular adaptations, and improves overall functional strength.

Using resistance training can involve various exercises targeting major upper body muscle groups, such as the chest, back, shoulders, and arms, which helps in progressively increasing strength over time. This creates not just an immediate improvement in upper body strength but also contributes to overall physical performance and daily activities.

On the other hand, cardiovascular training primarily improves endurance and cardiovascular fitness rather than strength. Yoga and Pilates can enhance flexibility, stability, and core strength, but they do not primarily focus on developing upper body strength to the same extent as resistance training. High-intensity interval training (HIIT) typically emphasizes cardiovascular conditioning and metabolic improvement rather than specifically targeting strength training needs. Thus, resistance training is the most appropriate and effective choice for building upper body strength in individuals starting with low strength levels.
