Meet Your Coach
Hi, I’m Karthick Sivakumar — an online fitness and nutrition coach with over 8 years of experience helping busy professionals transform their health, habits, and lifestyle through structured, virtual coaching.

My approach to fitness and nutrition coaching online is built on honesty, consistency, and small but powerful habit shifts — no fads, no extremes, and no generic plans.
Whether you’re just starting out or trying to get back on track, I’m here to guide you with structure, empathy, and the right push — through virtual fitness coaching for professionals who want lasting results.

Frequently Asked Questions
1. How does your online fitness coaching program work?
Once you sign up, you’ll complete a detailed intake form covering your goals, lifestyle, and preferences. Based on that, I’ll design a customized fitness, nutrition, and habit coaching plan — all delivered through our coaching app.
Each week, you’ll check in with me (your online fitness coach) to review progress, make adjustments, and stay accountable. Everything is done remotely, designed to fit around your busy schedule.
2. Is this online coaching program suitable for beginners?
Absolutely! Whether you’re completely new to fitness or restarting after a long break, this program is built to meet you where you are.
I’ll guide you step-by-step, helping you build confidence, consistency, and real results — without any extremes. Many of my clients are beginners who’ve never worked with a fitness and nutrition coach online before.
3. Do I need a gym or equipment for this virtual fitness coaching?
No gym? No problem. This virtual fitness coaching program is fully adaptable — you can train at home, at the gym, or even while traveling.
If you have equipment, great. If not, I’ll design a bodyweight or minimal-equipment plan that still delivers results. It’s 100% customized to your environment.
4. How do I stay in touch with my online fitness coach during the program?
We’ll communicate weekly through in-app messaging and scheduled check-ins. You’ll submit your weekly progress, and I’ll send video or voice feedback with updates, tips, and accountability.
If anything urgent comes up, I’m just a message away. You’ll always have support — no ghosting, no generic responses.
