Hi. I have literally just hung up my new heavy bag today, intending to get myself fit in a way that's more fun than just the standard gym workout. Should I be wearing inner gloves under my outer gloves? If so, what weight outer gloves should I use, and how do I find outer gloves to fit or are they all the same size? The gloves the bag came with as a set only just squeeze onto my hands without an inner glove or wrap. I would welcome some advice and pointers on what to buy. I am a larger, old guy, no longer particularly fit or strong. I'm happy to spend a little extra to protect my hands and joints. Thanks in advance for any advice on gloves.
