I opened them once, but cannot reopen, but have created my own exercises as follows:
SANSONE without weights 100 calories/15 mins
SANDONE with weights 125 calories/15 mins

RESPONSE PROVIDED BY LESLIE SANSONE:
Our walks always move at a brisk pace – we design the speed (miles per hour) of the walk by the beats per minute of the music – if you keep the pace of our walk and follow the arm movements at full intensity … you can burn at least 100 calories per mile … your body weight will determine if it will be a bit under this amount (a lighter body weight will burn less calories) …. others will burn over 100 calories because of a higher body weight … and don’t forget all those MUSCLE ACTIVATING Walk Boosters …. if you use hand weights, bands, belts …. you BOOST the intensity of the Walk …. you BURN MORE calories! The simple answer to “How many calories do we burn per Mile?” The Walk without Boosters … approx. 100 calories per mile! The Walk with Boosters ….. approx. 125 – 150 calories per mile! -

For the 14 minute mile, I do 7 minutes at 4mph and 7 minutes at 4.5mph under cardio. I am lighter so I don't think 100 calories a mile is accurate even with the extra moves that are being done. It always seems that most things that are guessing calories burned for an average person is done on someone weighing 180 pounds and since I am no where near that, I know I have to take that into consideration when I am logging or I could be giving myself a lot of extra calories burned. I am considering getting a heart rate monitor though and I really want to see how much it gives me based on that. I will update if I end up getting a monitor.

i do Leslie Sansone's DVD sometimes, I really like her DVDs I log them under walking 3.0mph mod.
