What is a recommended amount of resistance training for improving strength in adults?

Aiming for 2 to 4 days per week of resistance training is supported by various health organizations as an effective strategy for improving strength in adults. This frequency allows adequate recovery time between sessions, which is essential for muscle repair and growth. Resistance training promotes muscular adaptations such as increased strength, muscle mass, and improved functional performance.

Training within this frequency range also accommodates diverse fitness levels and goals. For most individuals, engaging in strength training two to four times per week strikes a balance that supports progress while minimizing the risk of overtraining, which can occur with more frequent sessions. It's important to note that training more than four days a week for most individuals may not be necessary to achieve strength gains and could lead to diminished returns and increased injury risk if not properly managed.
