this last week recovering has taken days instead of a single day after a workout. I'm getting the same amount of sleep and eating right...
the only thing that's changed is that i've added a single set to failure at the end of every workout per muscle group. Could it honestly make THAT big of a difference?
or could that one extra set throw me into overtraining?
Why change your training when you were doing so good?
Suggestion: Take 5 days completely off training, then get back on your old training protocol.
