If you're looking for an awesome leg workout, exercise machines are often overlooked.

These are the best machines to use to build your legs and a workout for which to use them. Do them in a circuit or one at a time.

Seated leg press (quads, hamstrings, glutes)
4 sets of 20 repetitions

Leg curl machine (hamstrings)
4 sets of 12 – 15 repetitions

Leg extension (quads)
4 sets of 12 – 15 repetitions

Seated leg press heel raises (calves)
3 sets of 15 – 20 repetitions

If you are on a time crunch, combine the leg curl and leg extension into a superset. Since you are working opposing leg muscles, rest between sets is not as necessary. Once you are done your first set of leg curls, stand up and move to the leg extension machine and repeat three more times.

HIIT finishers*
Get on a stationary bike or rowing machine and vary intensity for a one minute on, one minute off interval. Go hard for a minute, then dial back to regular speed for the next minute. Do so until ten minutes is up. This is a great Cardio Respiratory way to finish your workout.

*For those more advanced, push or pull a prowler loaded with appropriate weight for the same intervals, but rest during your down minute. Ten minutes of this will likely have you ready for the showers!
