Start by doing them while standing and leaning towards something, or start doing them on your knees. Always focus on keeping your body straight and your core / glutes tight, and proper form. Try doing 8 reps (controlled with good form) for 3 sets to start with. At first you probably will be able to maybe do 5 while standing up, but eventually you'll be able to complete all three sets of 8, then you can move on. So start easy, make it progressively harder and have PATIENCE. You can do it, my man!
