officialjerz: Dumbbell Bench Press The dumbbell bench press is great for your chest. What you will notice in this video is how much it also affects my triceps. With that, ALMOST ANY EXERCISE THAT EFFECTS YOUR PECS EFFECTS YOUR TRIs. So, while working on body sculpting it would be wise to not work triceps and chest on the same day. The movement is a simple natural movement of bringing the weight down and pushing it straight up. You only want to barely break a 90 degree angle. Anything 100 degree or more will put strain on your shoulders and could possibly do more harm than good (especially with higher weights). #happylifting #jerzfit
