Welcome to Fit Lizzio Fitness!

My name is Lizzy Ostro. Also known as Lizzio. Also known as Fit Lizzio.

I help men and women build a strong body, a strong mind, and strong glutes.

If you want to be physically strong, look good naked, have a nice butt, and be able to conquer the world in a positive way outside of the gym, you’re in the right place.

My goal is to show people that you can live your life to the fullest AND reach your fitness and health goals.

With 11+ years of experience and being mentored by some of the greats, I have a wealth of knowledge and experience to share. (Bret Contreras, “The Glute Guy” was my first coach and to this day remains a close friend and mentor)


I specialize in:

  • Strength Training
  • Glute Training
  • Physique Improvement.
  • I also enjoy working with athletes to help them improve performance in their sport.


In addition, I’ve experienced the deep lows of an eating disorder as well as the healing process. I understand what it’s like and what it takes to move on from that.

You can contact me at fitlizzio@gmail.com if you have questions or fill out my Coaching Application if you’re interested in working with me.

Fun facts:

  • I am a Music Lover and Sound Engineer. I work in recording studios and enjoy playing piano and guitar whenever I can.


  • I love wakeboarding and wake surfing. I will go any day, any time.


  • I also enjoy hiking, indoor bouldering, and walking on the beach with my cute-ass boxer, Oscar.


  • I love to travel and will take almost any excuse to get on a plane. I’m spontaneous and live my life saying YES. That wasn’t always the case, but my life has changed in ways I never knew possible by making this shift.
  • My favorite author is Chuck Palahniuk and I feel that he’s taught me more about life than anyone I know personally, besides my dog. I learn more about being a good, happy person from my dog than any human I’ve ever encountered.

Finally visited the @theglutelab yesterday for the first time! Such an awesome space and so many fun toys. Bret put us through a brutalllllllll workout and all 3 of us were 😅😳 the entire time. . ‼️In the first video, I’m using another version of the @the_hip_thruster most haven’t seen yet. Wayyyyyyy back in 2007, this was called the Skorcher and it was how we always did Hip Thrusts at Lifts. It felt soooo good to do them that way again. Definitely the highlight for me and brought back memories. I need oneeeee. . Here’s what @bretcontreras1 had us do: 1️⃣Knee Banded Leg Press (high and wide): 3 sets of 10-20, increasing weight each set. 1️⃣Forward Lean Hip Abduction: 3 sets of 10-10-10 Drop sets . 2️⃣Lever Reverse Lunges: 3 sets of 20 2️⃣RDL’s: 3 sets of 10 per leg . 3️⃣Banded Hip Thrusts off the Skorcher: 3 sets of 20 3️⃣Glute Ham Raise: 3 sets of 5 <—-I haven’t done these in probably 10 years and was terrified of them. Bret assisted me on them and I’ll probably start incorporating them because they’re great and I’ve avoided them for so long . 4️⃣BURNOUT: 3 minutes of Glute Bridges and Hip Abduction (I think I truthfully made it about 40 seconds and then sort of just flopped around like a fish out of water for the rest of the time 🤣) . . . #gluteworkout #gluteguy #eatliftthrive #strongwomen #glutelab #sandiego #northingtonfitnessandnutrition

  1. Hi Lizzy! My name is Jared! I enjoyed your about me section. From you competition photo I can tell you put in a lot of work to get that way.

    I do have one question. A while back I went running and I guess I did too much too soon. My left foot got tight and was like a bear claw. Well, since then it seems like now and again it gets tight, and I am not sure exactly what to do to correct this issue. I massage when needed and I use a tennis ball at least once a day. Do you have any suggests for me?

    Also, what kind of music do you enjoy playing and listening to?

    Thanks, Jared
