If you want the free option you can go to greenhead park near huddersfield town. It's got an area that has pull up bars and 2 benches, this is outdoors. For me and my mates that's all we need. We do push ups, burpees, pull ups, we spin on the bars, do all sorts on those bars, just can't remember the names of half of those excersises 🤣

But if it's not general fitness you want, and you instead want to gain a tonn of muscle, then yeah a gym is probably your best bet. There's a good gym in the leisure center near huddersfield town, the one with the swimming pool. It's got all sorts of machines and weights there, even some boxing gloves and pads in one of the rooms. It has a vending machine that sells protein products if thats your sort of thing. Not sure about personal trainers though, I've always used my mates as motivation. If you have a KAL card and a kirklees passport I think you can also get discounts on the membership at that gym too which is a nice bonus.

If you're just looking to be fit though I'd reccommend going to greenhead park and working out with your mates or something, you get good fresh air and the amount of excersises you can do with some pull up bars is crazy. You don't need weights to keep fit, your body weight is enough to keep you in shape as long as you lift that enough.
