@defd2000 If you’re looking to save money, you can find a cheaper gym if there’s one around.
If you want to put on muscle, lifting is the easiest way, along with diet.
Currently I’m spending for myself and my mrs about 400 every 3 months for boxing, 110 a month for our gym.
Food isn’t biggest concern is health AND performance, so I eat clean, I do have a day a week I’ll eat something that makes me happy, probably spend 400 a month on groceries.
As for supplements, the must haves, krill oil, greens powder, CoQ10, magnesium, zinc and for me melatonin cause my sleeps crap.
If you love group classes and they make you happy, then stay with it.
The most important thing is your health, and finding a trainjng method you actually enjoy and can stick with !
