While there are many do it yourself training tools you can make for little or no cost to help with your game, here are some of the primary pieces of equipment you will need to train.
Heavy Bags are great for training at home outside of class. Heavy bags and bag stands usually start around $120 , but keep in mind you will need several weight plates to prevent the stand from tipping or falling over. Heavy bags may also be used in conditioning for throws and groundwork. If you plan on doing a lot of training at home, this would be a worthwhile investment.
These are great tools to work technique when no live partners are available. Some are suitable for striking and throwing practice as well. Prices vary on grappling dummies dependent upon features such as free standing, joint articulations and materials. Like most training gear, if you do your homework and competitively shop, think about your training gear as a long term investment. Over the long run, that is a small price to pay for a training partner that is ready whenever you are.
Mats are a great investment if you are going to be doing a lot of throwing, takedowns or groundwork. Like throwing dummies, they can be a costly at first, but with proper selection and care they can last decades.
