So I stopped going to the gym for financial reasons and wont be able to start again till next year in spring. My question is what's the best training workout I can do at home so I can keep getting better or at least keep fresh. I can only spar and do mitts once a week. My guess was shadowboxing but I also have a double end bag and a heavy bag. So which out of the three should I work on the most? All tips appreciated. Thank you for reading
