Killer Leg Workout by a Minneapolis-Based Personal Trainer

Killing Your Legs One Exercise At a Time

Tonight I killed my legs in 20 minutes flat.  A lot of people believe a workout has to be 40 minutes or an hour to be a difference-maker...this is not the case.  I only had 30 minutes to go through a workout (warm up for 5, workout for 20, stretch and cool down for 5).

To kill my legs in the small amount of time I had, I opted to alternate between quad and hamstring exercises, mix in some calfs, and not rest for a second.  Here is what a personal trainer killer leg workout looks like tonight!

Killer Leg Workout Exercise Group #1

Weighted wall squats with swiss ball-holding 12K kettlebells in each hand, I lowered into a wall squat, with a swiss ball supporting my back...knees at a 90 degree angle.  I held this position for 30 seconds (holds are great for any muscle group because they stimulate every type of muscle fiber we have!), rested in a standing position for 10 seconds, then back down for another 30 second squat.  After three 30-second squats, I went onto...

One-legged lying leg curls with swiss ball-lying on my back with my right foot on top of the swiss ball and my butt off the ground, I curld the ball toward my body by using my hamstrings.  15 per leg. Ouch, these hurt.  After 15 per leg, I went to...

Killer Leg Workout Exercise Group #2

Weighted Bosu Ball Squats-standing on the black side of a BOSU ball, my feet shoulder-width apart, I squated while holding 12K kettlebells.  After 15 slow and steady reps, I did...

Leaning Leg Curls-Kneeling on my knees with my arms crossed and hands on my shoulders (with partner holding down my heels), I leaned forward while keeping my back straight, and used my hamstrings to curl back into an upright kneeling position.  5 reps of these was enough before I went onto..

Killer Leg Workout Exercise Group #3

Running Stairs in Place-I climb the lowest stair fast for 15 seconds, rest for 5 seconds, and climb the second-lowest stair for 15 seconds, rest for 5 seconds, and repeat one more time before I do...

Quick Jumps Over Resistance Band-With a band laying in a straight line on the floor, I jumped with both feet from left-to-right and back for 15 seconds (as fast as I could), rested for 5 seconds, jumped forward to back with both feet for 15 seconds, rested for 5 seconds, jumped left-to-right on my right foot for 15 seconds, rest for 5, then left-to-right with my right foot.

And then I repeated this circuit two more times through!!!  Talk about a tired, sweaty, legs-killed mess.
