She's not overweight, which you may have meant, but she did up her exercise regimen which indubitably increased muscle diameter ("bigger") and muscle strength.But, essentially, [Virtue] upped the ante in off-ice workouts from her already-rigorous regimen and altered some basic mechanics of her skating stroke — which few skaters in their 15th year of competition ever do.
“We tried to focus on taking the load off my calves, activating and recruiting different muscles,” Virtue told The Spectator.
Is she fat? Heck no.
Heavy has a lot of different connotations, but this time, it wasn't used in a "fat" context. It was used more in a "she's stronger" context.
("Heavy" doesn't necessarily translate to "overweight". I mean, you wouldn't call a UFC fighter with tons of muscle overweight without hesistation, would you? BMI is just a little obscure in that way.)
Besides, muscle hypertrophy is less pronounced in women than in men. She really doesn't look that much more buff and it's nice to see that the changes in her strength training allowed her to forgo surgery in her legs.
ETA: BUT if you said this in response to let`s talk, then I am not defending that person.
