Yesterday's arm workout was effective, however, I had to do far more reps than I had expected to.
I'm going to make more of an effort to concentrate on my form. I tend to rush the reps rather than isolating the muscle properly. Consequently I ended up having to do many more sets than I should have done. I also really need to get some adjustable dumbells, a single 35lb weight is almost pointless.
In other news, I'm going to take the exercise bike apart, yet again, and see if there's any way that I can add a washer to preven the drive belt from falling off. If not then I'm just going to have to take the plunge and buy a new one.
