I found out that buying dumbbells is about $1 a pound. I like my dumbbells, but I needed a 15 lb set which would've cost me $30. The Ultimate ProGym has a 5, 10, and 15 lb tube. So I can use these alone or combine them for 5,10, 15, 20, 30 lbs resistances.
I like this system as its GREAT for people who travel as everything fits into a little bag. You never have to worry about stubbing your toe on them in the night.
The down side is they don't identify which tubes is what (red is 5, green is 10, and blue is 15), and if you are doing cardio they may not be as flexible to use as you do a lunge with weights (as you need to hold down the tube with your feet).
You do have a great attachment that allows you to strap the tubes to the doors that allows you to do rowing, bench press and more. Another attachment allows you to strap the tube to your ankle (great for working your leg).
I did a test with a 10 lb. dumbbell and the 10 lb. tube. The great thing is you control the resistance with the length of the tube. Using this I can make the 10 lbs tube feel less than 10 lbs, just like 10 lbs, or if I shorten the tube heavier than 10 lbs.
Polar Heart Rate Monitor Overviews
I have a polar F6 heart rate monitor. I had an F11, but must've got a “bad one.” So I exchanged it for the F6. This is the third polar unit I've had. The bad news about Polar units is it costs at least $75 to have new batteries installed.
I have found that Omron makes makes the HR-100C unit which is around 32 bucks. While it doesn't have all the bells and whistles of a polar unit, it does track your heart rate, and an alarm sounds if you go above or below it. The great thing is both the transmitter and the receiver have replaceable batteries. Consequently, you can have this unit forever.
The bonus of keep track of everything
I recently busted through a plateau, and lost weight three days straight and I knew that today I would show a gain. Why? Because looking at my history it's what I always do. If I wasn't tracking my weight, this might've been something that set me back. However, since I can see my history I know this is my body acting the way it always does.
