Resistance training has a profound effect on muscle tone by enhancing muscle strength and endurance.

Moreover, resistance training helps boost metabolic rates, contributing to fat loss and increased muscle visibility. Regular engagement in resistance exercises is essential for developing a balanced physique and maintaining physical function as one ages.
