html

<button type="submit" @click="addselectbox">add select box</button> <div v-for=" customizedexercise in customizedexercises" class="input-group">  <span class="input-group-addon"> <select class="selectpicker form-control"  v-model="customizedexercise.name"       name="name" id="name">      <option value="{{ exercise.name }}" v-for="exercise in exercises">{{   exercise.name }}</option>  </select>  </span>  <span class="input-group-addon"> <select class="selectpicker form-control"  v-model="customizedexercise.sets_duration"  name="sets_duration" id ="sets_duration">      <option v-for="number in numbers" value="{{number}}">{{number}}</option>  </select>  </span>  <span class="input-group-addon"> <select class="selectpicker form-control"  v-model="customizedexercise.weight"   name="weight" id="weight">      <option v-for="number in numbers" value="{{number}}">{{number}}</option>  </select>  

{{number}}

<input type="hidden" name="exercise_day_id" v-model="customizedexercise.exercise_day_id" id="exercise_day_id" value="1" /> 

route

route::post('/api/customized-exercises',function() { $inputs = request::json()->all();  return $inputs;   }); 

you need pass array of objects json before sending on php.

customizedexercises = json.stringify(this.customizedexercises);
