When there is little time for practice you can use your mind to find different ways to keep healthy. for example to keep the joints healthy you can lie on your back and move all of the limbs and neck and torso all at once and in different patterns and ways. Than you do the same on your stomach and this will improve your overall awareness and ability to be free. Another way to do this is to find simpler ways to learn your movement.
Walk up and down a wall or a partenr using your hands and later your fists as well and than do the same using your feet and legs. Walk in a squat keeping the feet flat and the posture relaxed and upright to relax the entire body and build endurance and than have pushing games with partenrs to learn to blend with others motion and stay alive in a mass. Have a partenr hold your legs and walk using your hands and torso to navigate and than play with your partners in dropping them in the ground within this state to better use your arms and hands. Do the same as your partenr holds your arms behind you and you use your feet to drop your partner on his or her behind and remember your spirit and purpose will make the movement what it is. This is but a small glimps of what can be done. It is up to you to find yourself within the way.
