weird gym machines

I rarely go to fitness gyms, but I went to one yesterday. It had a whole lot of fancy Cybex machines. Impressive.

The bike gave a heart rate readout without any sensor to attach to the chest. Is it realistically accurate? Does it sense through the handlebar or something, or does it have some kind of proximity sensor?

It also had a power readout. Is this reasonably accurate? Of course, the power reading would increase when I increased resistance or crank speed, but crank speed had less effect than I expected. Does that mean anything?

I realize the mileage it reports is merely as a guide for comparing with your own performance but it seems that the power might be more meaningful.

I think I've seen exercise machines with metal pickup plates on the handlebar grips. You may need to grab both sides.

I don't know why that wouldn't be more common in the bike world.

There was a thread with some lady asking why her HR is 210 on the elliptical and if it means she's about to die. Consensus was HRMs on gym type exercise machines are not reliable.

Many of these machines will also respond to a chest strap, the newer ones to either Polar or ANT+.

You could watch the power output and change cadence. If you double cadence at the same resistance, power should double. I've used new gym bikes which seemed to give reasonable power output numbers.

Right. I increased cadence by 20% and the power readout stayed the same, so I thought it was a bit strange.

I probably won't use a machine like that often, so it doesn't matter, but it was interesting. I imagine the measurements are useful for comparing sessions but not for knowing precisely what I did.

At the gym, I wear a strap and some sort of HRM that uploads to where I record my workouts. So I have a pretty good idea of training stress no matter what I'm doing. The training stress of weightlifting will be underestimated, but it works well with cardio equipment.

I recently purchased a Polar FT7 HRM which comes with a chest strap. My issue is that the bikes at the gym do not all pickup the output from the chest strap. When they do as you can imagine, they are dead on. I use the Keiser brand stationary bikes and am amazed at how well the duplicate the road bike experience. So far I have found intervals to be the best training. Take my HR up to 135 and then back down to 99. I am able to do this a minimum of five times an hour. Based on the amount of perspiration this causes I am confident I will benefit from this when I get back outside.

If the bikes are all the same, it's usually low batteries in the pickups. You could have gym staff check that.

Thanks Carbonfiberboy, will replace battery could have been around for awhile even in a new transmitter. An inexpensive way of getting back functionality. Workout intervals seem to be the ticket for heart fitness.

Not your strap's battery. The batteries in the bike.
