Kelly Osbourne’s Workout For 75 Pounds Weight Loss

Kelly  Osbourne was no stranger to her local gym during the 75 lb. transformation and would hit the gym regularly to blast away calories and sculpt her body.

Kelly’s trainer had her on a four times per week workout regimen that was designed to sculpt and tone her lower body muscle groups and burn a ton of calories through intense cardio sessions.

Osbourne Workout

She would typically workout around 12 Pm and then would eat lunch afterwards.

Here is a look at the Kelly Osbourne Workout Plan:


Monday and Friday: Lower Body and Core Resistance Training Workout


Exercise One: Squats

Sets: 3-5

Reps: 10-15

Kelly would do high intensity squats and keep her repetition range in the 10-15 range for perfect fat burning and muscle toning results.


Exercise Two: Db Lunges

Gym Routine

Sets: 3

Reps: 20 total

This was pure torture for Kelly! Kelly admits this was her least favorite exercise and she would feel a deep burn in her glutes, thighs and hamstrings after this intense lower body exercise.


Exercise Three: Bicycle Crunch


Sets: 3

Reps: Failure

The bicycle crunch is one of the best abdominal exercises for muscle toning and definition in the lower abdominals and oblique’s. Kelly would transition right from the db. lunges into a main core sculpting exercise.


Exercise Four: Hamstring Prone Curl


Sets: 3

Reps: 10-15

Kelly would do the hamstring prone curl to sculpt the back of her legs and butt. This was a staple exercise in her regimen and is the reason that many people accused Ms. Osbourne of having a Brazilian butt lift! Now that is some serious results when people accuse you of going under the knife.


Exercise’s 5 and 6: Leg Variety


Kelly would typically end the workout with a few different lower body exercises to further increase her metabolism and muscle toning. Some of her go to’s was wall sits, leg extension, leg press, hack squats, and burpees.



Tuesday and Thursday: Cardio Confusion


Tuesday and Thursday consisted of 45 minute cardio workouts. There wasn’t much of a strict plan with the cardio workouts other than the fact that she had to get her body moving and break a sweat for the majority of the time.


Kelly would switch up her cardio routine all the time and one day she would go bike riding, then if it wasn’t nice outside she would sometimes head to the gym for an elliptical training session.


All that mattered to Kelly on her cardio days was that she did something she enjoyed and didn’t take it too seriously. Her trainer warned her that if she stuck to only doing cardio she didn’t enjoy she wasn’t going to stay on track – so Kelly focused on physical activities that she enjoyed liked bike riding, swimming, hiking with friends, and even an occasional tennis match.


That is the blueprint on how the beautiful and now slim Kelly Osbourne lost a whopping 75 lbs! Make sure to take some notes and follow her advice if you are looking to make this year the best ever for weight loss!
