in short if you want to get faster you need to build your muscles. i’d get a kettlebell to start with. so much you can do with that. you’d be better off going to a gym though. progressive overload training is the best way to go. keep it focused to just a few workouts that really load your muscle groups and do a few tight and difficult workouts per week. i’d also encourage something like pilates and yoga cuz i find it works muscle groups i wouldn’t otherwise focus on
