If you want to build some muscle and gain strength, then find weights you’re comfortable with in different exercises.
But Trace had a good point to. Body weight workouts are incredible. I did three months of nothing but body weight exercises and I looked and felt amazing. But nowadays I’m adding weight to what I do; put a disc weight on my for pushups and put on a weight belt for pull ups, etc.
But I think a good way to measure strength before you jump into workouts is to test your fastest, your max bench press, and how many pull ups you can do. The reasonnyou want to do that is so you can do it again, in a month. It measures your progress and strength, and makes you feel good that your gaining.
Just start off with some lighter weights and make sure you’re able to push yourself to do one more each time.
