http://www.beachbody.com/product/fitness_programs/hip_hop_abs.do?view=fullsiteWork out modifications for beginners or injuries.1. Go at your own level and speed take brakes if you need to. ( if something is in the time of 8 you can do in the time of 4 or so on)2. If it hurts don't do that movement. 3. If you are very over weight go easy on yourself and your body.( you may be moving 100 more pounds than the skinny minis in the video so honour that)4. For injuries ( I have back) I personally avoid long reps on one side. I just alternate or move to the other.5. Take the bounce out. Stay lower on movements.6. Start with low or no weights.7. Ice injuries and look into modifying the movement that caused it.8.keep moving and rest when needed. But the key thing is keep moving. 9. Learn what works for you.10. Be kind and patient with yourself. I lack coordinationbut still have fun trying :)
