Vanessa's story, in her own words

Vanessa started training with me in January 2026. Her goals were to lose weight, work out consistently and become healthier, focused in weight loss and building muscle.

Here is what she says:
"Since working with her, I've lost almost 50 pounds and have seen major improvements in my strength, mobility, energy, and overall health. After just one month of training, I got my period back, and my cycle has since become regular again despite my PCOS."

Swipe to see her training, specially the clips marked before and after and see her evolution. I'm proud of the work you put in, Vanessa! ❤️

If this resonates, drop a comment. Every story starts with showing up.

A small form cue can completely change how an exercise feels.
For dumbbell rows, focus on pulling the weight toward your hip while keeping your back flat and your core engaged. This helps your back do more of the work instead of relying only on your arms.

our low back hurts during leg raises? Try this

Leg raises are a great core exercise, but when your low back hurts every time, something in the form needs adjusting. It's more common than you think, and with the right form we can get it. First, make sure you're not arching your back. Rotate your hips so your pelvis is tilted backwards, and keep your back touching the ground.

Still a challenge? Modify it with a Pilates ball: place it under your sacral region (your low back) and perform the exercise. The ball tilts your pelvis for you, so you can focus on your core.

This is just a way to modify the exercise, so keep working on fixing your anterior pelvic tilt too. Save this for your next core day and tag a friend who would benefit from learning this exercise.

Feeling your RDL in your back or quads instead of your hamstrings and glutes? Start here.

The RDL isn't an up and down movement, it's a hip hinge: your hips go back while your chest goes forward. A wall gives you instant feedback. If your butt touches it, you're hinging, if it doesn't, you're probably bending the knees. Once the pattern feels right, squeeze your glutes and keep them squeezed all the way up.

💡 Try this if you feel it in your back once you add weight: keep the weight touching your legs. The further it drifts from your body, the more your back has to work.
