Hey guys I am new here. I 've got the following routine: 1st day legs and delts, 2nd day chest and triceps and 3rd day back and biceps. I want to level up and try some strength exercises such us: deadlifts, bench press, squats, shoulder press, sled drag etc. Do I have to change exercise routine? Or I can add them to right day? (e.g.: squats to the leg day and bench press to the chest day). If yes, how to put the others that require the whole body (e.g.: deadlifts, sled drag) ?
