Online coaching session are weekly (30 minutes) and progress is based on your pace. I look forward to meeting with you.

Why should you work with me?

Working with a personal trainer is a big decision. You are taking control over your health, longevity and vitality. Exercise is the best medicine that we often overlook or don't know about. My background of 16+ years of exercise and fitness give me an unique approach and perspective. I have extensive experience with working with individuals of all age levels and health concerns. I adapt and adjust for what your body needs based on your specific fitness goals. Movement assessment and pain-free movement are the foundation of building strength. We progress at a pace that fits your season of life and your lifestyle. Most of my clients are busy and have many demands on them, they have decided to prioritize their health and fitness so they can do all the things they want to do. We always consider other factors in your training like sleep hygiene, nutrition, hydration, stress management and non-structured physical activity. I do not do cookie cutter programming or fads. We stick to safe, effective and efficient routines that get you to your goals.

High Intensity Interval Training is a bodyweight workout that requires a base of strength and aerobic conditioning, good stability and no injuries. The class always offers options for low-impact and focuses on form over fatigue. All ability levels are welcome and anyone new should go at 50% intensity the first time to see how it feels. Experience a great workout and improve your energy management.  Focuses on cardio strength and core. Heart pumping, air gasping drills intended to drench you in sweat and maximize your training time. Class has a proper warm-up, main routine and cool-down. The HIIT routine itself is very short (so you can be Powerful).

This Bootcamp workout is a mix of strength and cardio targeting the larger muscle systems. Fun drills and themes to torch fat, tone, and shape your butt and legs. The exercises are dynamic enough that they engage the core muscles (abs, lower back, obliques), as well. All levels welcome!

We often use some equipment. Like DB's, circle bands, or on rare occasion gliding discs.
