Gabriel's unusual sparetime occupation comes from the fact that frogs are migrating these days, which means you'll find plenty of frogs on the roads these days who risk being run over.
"I'm just trying to do as much as possible, and I hope I can have some impact. Saving hundreds of frogs every day can be a big deal", says Adam Gabriel to TV Midtvest.
He claims to have saved over 250 frogs, which he has released into a small lake in the area.
The 23-year old Czech international criticises the Silkeborg Municipality for not doing more to protect the frogs. He has proposed to build barriers that leads to a bucket in the ground which is a solution widespread in his home country.
"It is not expensive, and I think it is a fairly simple solution. And if there are a lot of frogs, then I think it is worth it", says Adam Gabriel.
Mathias Henneberg, head of water and nature at the Silkeborg Municipality, praises Adam Gabriel's efforts, but at the same time says that it is difficult for the municipality to save all the frogs.
"It is the same challenge that is faced by all sorts of different species. It is in the animals' nature to migrate, and sometimes they also cross the roads", he says.
The football player has shared videos on Instagram in order to help more frogs.
For the Silkeborg municipality its extra special that a wide known football player now puts focus on the problem.
"It's amazing. It's always great that someone who is a role model for young people is taking the lead", says Henneberg.
Adam Gabriel says that he also plans to spend both his Friday and Saturday evenings to save more frogs.
"This is my thing and my activity. And I hope that someone can help me and that we can solve the problem for the future", says Gabriel.
