I do VERY low intensity on the bike, I really don't think its a problem. I mainly just do it to get my blood flowing a little bit and get my legs moving. I could perform complex mathematical equations no problem at the intensity I'm doing the bike ;-)BluEyes said:Lose the 5 minute bike before squats. It's okay on other days, but that biking chews up your quads and drains glycogen stores before you even start squatting.
Try a 5 minute fast walk/jog on the treadmill as a warmup.
If you're cycling because you think it'll prep the quads for squats, its a mistake. Your warmup sets(using bar only, etc) will be sufficient.
The one day I skipped it, my legs felt like **** the second set through squats and hurt the rest of the day and most of the next. The bike has been working for me pretty well, and I would agree with you if I didn't know exactly how low intensity I was doing it.
As an update: after reading lots about burning fat while building muscle and posting a thread asking for suggestions, I am doing to be changing my diet / routine as follows:
6 days a week I'm going to add a 30 minutes low intensity treadmill session in the morning. I'm going to reduce my total caloric intake to about 2500 from about the 3100-3500 that I try to get now, so I'll still be at a slight surplus over maintenance but not much. I'm expecting this to slightly slow my growth but still (hopefully) allow me to maintain my scheduled lifting gains for the most part, and increase my fat loss considerably.
