This is one of my favourite compound sets for the legs, especially targeting the thigh and glute muscles.
This will not only get a serious burn going in your legs, it will ramp your heart rate up.
I like to do the following:
a) Rear Foot Elevated Split Squats - 10 reps each side
b) Goblet Squat - 10 reps
You're not limited to that too, for example you could do 6 - 8 rep sets or go as high as 12 - 15 reps.
The other good thing is that you only need 1 pair of dumbbells - Select what you can handle for the 10 reps on split squats and then put one weight on the floor and complete the goblet squats with the other weight.
This is my, mostly, Personal Trainer musings and information which I hope you'll find helpful!
