My workout room is right next to the room where my son sleeps. He's 4 years old. Sometimes I would like to workout either after he goes to bed, or before he gets up in the morning. But we have hardwood floors in our house and I'm afraid the jumping in vids like in the Imaxes would be too noisy and wake him up, or prevent him from going to sleep. Would puzzle mats help to insulate the hardwood floors from noise/vibrations? Just mulling this over. Any opinions? - Sarah
