As a term of my employment as a trainer at my gym, I had to buy and use a bodybugg. It’s a small device that you strap to your arm so that it rests on your left tricpes. It measures four things:
Your body temperature
Your body’s ability to disperse heat
How much you sweat
Movement through an accelerometer
Basically, I’m wondering if this will provide for an accurate count of my daily caloric expendature. There’s definitely a difference between workout days and off days, but I have trouble believing that this could be really accurate for me since my exercise is intense lifting 4-5x a week for an hour, and that’s definitely not a normal way to exercise (compared to the mouthbreathing masses).
Here’s a screen grab from my last leg day. I’m a 21 year old male, 240lbs, and about 25% bodyfat (though I’m not sure, no one at my gym can do a proper caliper test). Diet is low-carb with 1 carb-loading day per week. Clean food all week. The workout was this:
Barbell back squat:
135 x 10 (warmup)
185 x 20
225 x 15
245 x 10
205 x 10
185 x 10
Machine hack squat supersetted with walking lunges, all lunges sets were 10 reps per leg w/ 60lbs:
225 x 10
245 x 10
245 x 10
265 x 10
225 x 10
Machine leg curl:
160 x 10
185 x 10
185 x 10
165 x 10
155 x 10
Machine leg extension:
185 x 10
185 x 10
170 x 10
175 x 10
165 x 10
Calf raise
185 x 20
185 x 20
160 x 20
160 x 20
125 x 20
110 x 20
All rest periods between sets were 15 seconds, and all rest periods between different lifts were 2.5 minutes (except between the hack squats and lunges).
Here’s a screengrab from a non workout day. It was a Thursday, and my last workout before that one was on Monday, so EPOC shouldn’t have been much of an issue.
I was a trainer at a gym that sold them and have used one. They seem to be pretty accurate and clients who use them on a regular basis lose more weight than other clients. On a side note I don’t think you need a carb day IMO… 25% is pretty high to be using a refeed.
I’m starting to think this thing sucks ass. I’ve been utterly meticulous about logging every single thing I eat, and despite the bodybugg system showing me at an enormous deficit (2k kcals a day most days) my fat isn’t budging.
I’ve cut calories by another 1k a day, and I’m now doing fasted cardio in addition to all my lifting, so that should get it back on track.
Still though, does anyone have any experience with the bodybugg? Is it as inaccurate for me as it is for most others?
