I would say app but I am not likely to take the ipad to the gym - today I saw a lady's iphone detach from her person while she was on the treadmill and go flying across the room. I suppose I want to put together a little schedule to know what I should do, for how long and how fast. I like the treadmill, cycle, wave machine, cross trainer etc not really weight training as it gives me two days of soreness
. I know you can sort of program things in but it does not seem convincing to me for example, on the wave machine today it was telling me to maintain a speed of 180spm but even when I tried it seemed impossible to get up to even 80 mainly bc of how it bloody works! Therefore, I assume the calories burned displayed at the end was inaccurately high. I am not very good at the maths, I would be willing to invest in a small add on gadget.
