The only problem is that you are using the wrong object to iterate.
if you run this snippet you can see the returned object on the console.
$.ajax({ type: "GET", dataType: "json", url: "https://wger.de/api/v2/exercise.json?category=8&language=2", success: function(data){ console.log(data) } });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
as you can see, you need to iterate over data.results , so this code should work:
$.ajax({
type: "GET",
dataType: "json",
url: "https://wger.de/api/v2/exercise.json?category=8&language=2",
success: function(data){
if(data.results){
$.each(data.results,function(index,object){
$("body").append("<div>"+object.name +"</div><br/>")
})
}
}
});

The data argument supplied to the success callback comes in as an Object with a results property that is an Array of Objects.
Rather than passing in the whole data object to $.each you should just give it the results array like so:
success: function(data){
$.each(data.results, function(index, object){
$("body").append("<div>"+object.name +"</div><br/>")
})
}
