Hopefully I'm asking this in the right place. If I'm not, please let me know where to go.
I'm already physically active, and have been running twice a week and doing various exercises (push-ups and several variations, sit-ups, that kind of stuff - and I take Krav Maga twice a week), but I want to take it to the next level and get some good muscle definition going. I'm not looking to get buff or bulk up, I just want to be more fit and toned - arms, chest, abs, the usual suspects. Would it be more beneficial to me to get a gym membership, or would it make more sense to purchase a set of dumbbells and a bench of some kind and do various exercises at home? It seems to me it's cheaper in the long run to do dumbbells and a bench, but of course the equipment at the gym is more varied. I'm not totally sure which is better for my goal, or what the key differences are.
If it seems like dumbbells and a bench might be better, what are some of the better options? If its a gym, which things should I look for when searching for a place to try? And what sort of progress can I expect from either in relation to various muscle groups?
I also don't have any sort of app or training program or anything. Is there anything out there that would help me keep track of anything worth keeping track of that I can't do mentally?
Even though I'm physically active, I'm a complete newbie when it comes to weights and gyms. I'd really appreciate any help you guys can offer.
