Duration: 20 Minutes
Equipment: Heavy Dumbbells
This lower body strength workout will tone your legs and is knee friendly at the same time. You can use dumbbells like me in this workout to spice things a bit up and get more challenged. Although the lunges and squats are very undeep, you will get challenged because your balance will be challenged at the same time. This will results in improved strength and balances, and also tones your legs at the same time.
