Redirect to a link after selecting a checkbox and a 'Next' button

I need to redirect users to a page (multiple options) after they select a checkbox and only after clicking the 'next' button. Here is my code with three checkboxes (sorry i can't add picture yet:

          <form class="q2" action="">
                <div class="form-group radios">
                    <label for="1">
                    <input type="radio" name="physio" id="1"><span class="checkmark"></span>
                        Mark
                    </label> 
                </div> 
                <div class="form-group radios">
                    <label for="2">
                    <input type="radio" name="physio" id="2"><span class="checkmark"></span>
                        John
                    </label>
                </div>
                <div class="form-group radios">
                    <label for="3">
                    <input type="radio" name="physio" id="3"><span class="checkmark"></span>
                        Jack 
                    </label>
                </div>
            </form>

                <a href="poids-ideal-chat.html">
                    <div class="button-icon next cta src">
                        <p>
                            Next 
                        </p>
                    </div>
                </a>
