I have provided a more comprehensive training workout that you could be doing at home to begin getting in shape for the coming season (see workouts). Here is an even easier workout to follow (starting this Monday) ... Try to do this at least 3-days this week. Get a teammate to go do the workout with you. It will help you pace the rest between by alternating who goes.
You can use socks, rocks, rags, .... anything in place of cones. Be sure you are doing these on flat surfaces that don't have holes/divots that you could injure yourself on. Grass surfaces are good. If you can get to the beach and do them in the sand that would be best. NO CLEATS!
