For boosting metabolism without excessive sweating, yoga would be the most suitable option among the exercises listed. Yoga focuses on stretching, strength, and relaxation, which can enhance muscle tone and metabolic rate without leading to intense sweating. Additionally, certain styles of yoga, like power yoga or vinyasa, can be more vigorous, but even gentler forms can help improve metabolism over time.
Dancing could also be a good option, as it can be fun and may not always lead to heavy sweating depending on the intensity. However, yoga is generally more associated with increasing flexibility, strength, and metabolic benefits without the potential for high sweat levels seen in running or weightlifting.
