Karin Larven is a 27-year-old Estonian fitness enthusiast who only started taking the gym seriously a couple of years ago. In this interview, she talks about her journey, her diet and how to get started in a way that makes exercise a lasting part of your life.
At a glance: 168 cm, 66 kg, 4–5 strength workouts a week, calories tracked on weekdays and a more relaxed approach at weekends. Her biggest personal achievement, she says, isn’t what she can lift, but her decision to launch a YouTube channel.
How Karin Larven found her way to the gym
Karin started out as a teenager with group fitness classes that included plenty of exercises similar to those you’d do in the gym. Several years followed when, by her own account, she wasn’t particularly physically active. It was the gym that got her back in shape — and only quite recently, over the past couple of years.
She’s honest about not considering herself naturally athletic. That’s precisely what makes her story interesting: someone who hasn’t always been involved in sport finding their rhythm as an adult is far more relatable to many people than a trainer’s professional CV.
She considers starting her YouTube channel her biggest achievement. Not a lifting record, but a step outside her comfort zone. Sometimes that’s enough.
Karin Larven on her weekly workout routine
4–5 strength workouts a week. Each workout lasts about an hour and includes 4–5 exercises. The emphasis is on consistency rather than big numbers.
Her training split is simple: lower body and upper body. She doesn’t devote an entire day to a single muscle group. This works well if you want to see results without spending your life training. With two upper-body and two lower-body days, you can train each muscle group twice a week — a sensible minimum for hypertrophy.
Her YouTube channel has two workout plans you can download for free, with more detail on exercise selection — one for the lower body and one for the upper body.
Karin Larven on her approach to nutrition
She counts calories on weekdays. It doesn’t suit everyone, but it works for her. She describes her diet as “pretty normal”: plenty of fish and meat, with roast potatoes, rice and buckwheat flakes for carbohydrates. She eats vegetables and fruit a couple of times a day. Something sweet makes its way in every day — and she doesn’t make an issue of it.
She doesn’t count calories at weekends. She allows herself more “junk” and dishes that she says are good for her mental health. It’s a deliberate choice, not a lapse in discipline. That contrast — measured weekdays and relaxed weekends — is precisely what keeps her going in the long term.
Favorite foods: home-cooked Estonian dishes and tempura sushi. She says she isn’t a picky eater.
Tips for beginners
1. Start slowly. 1–2 workouts a week. If you plan 5 workouts a week, the routine often falls apart by the third week — leaving you disappointed rather than fitter.
2. Find a type of training that suits you. You don’t have to enjoy running or going to the gym. For example, Sparta Sports Club offers a wide range of group fitness classes where you might find something you enjoy.
3. Take progress photos. You won’t see the change in the mirror — but you will in photos. At a crucial moment when your motivation is wavering, seeing the difference in photos taken two months apart does more than any pep talk.
Karin also makes a point of saying that her biggest source of motivation is herself. The goals she sets and the question, “I wonder what else I can do?”
