That sounds a bit like dodgy science to me, whereabouts did you read that? I thought the professionals split their routine so that they could get their energy back and do two serious workouts per day. However, you must be doing something right if you're shifting those kg.
I generally work out for 50 minutes to an hour, but that is generally because I'm absolutely knackered by about that time. It is enough to let me hit two muscle groups from three different angles
40 minutes is ideal, but its when it gets over an hour that it becomes too much of a problem. Sometimes less is more.
I would also highly recommend Skip Lacour and Jeff Willets DVDs to anyone. Great information for naturals looking to get the quickest results.
'Cortisol is a stress hormone that's released during bouts of training. Some is needed, but too much cortisol, especially if it stays elevated after the training session, can greatly decrease muscle growth and strength improvements.
Cortisol is catabolic, meaning that it leads to the breakdown of stored substrates. During exercise, this can be useful since it'll breakdown stored glycogen into glucose and stored fat into fatty acids to provide energy for the working muscles. However, post-training it'll continue to breakdown glycogen which slows recovery. It also breaks down muscle tissue into amino acids, making it harder to add muscle mass.
Furthermore, since both cortisol and Testosterone are both made from the same raw material (pregnenolone), constantly elevated cortisol levels will eventually lead to lower Testosterone levels.
Cortisol output during training has been correlated with training volume; the more work being done during a session, the more cortisol is produced. This is especially true when metabolic-type training (high reps, short rest intervals) is used.
To avoid overproducing cortisol, you want to keep your sessions short, around an hour or less.
Another reason to avoid long sessions is related to mental focus. Regardless of how much you love training, at some point your focus will go in the crapper during a long session. The work performed in that state will be unproductive and could even lead to bad habits that'll screw you in the long run.
You can train more than one hour per day, but split your daily volume into two workouts. In fact, splitting your daily workload into several shorter sessions is much more effective, as it leads to both lower cortisol production and higher Testosterone levels. It's been shown that when two daily sessions are used, Testosterone production is higher after the second workout than after the first.'

another:
'The 30 to 40 minute workout offers the following benefits:
- It's much more feasible to maintain maximum mental and physical intensity for 30 to 40 minutes than for 90 minutes. In fact, after 30 minutes mental focus and intensity start to decline rapidly.
- Training for 30 to 40 minutes maximizes hormonal spikes related to high-intensity training. Max-OT training maximizes key hormonal output based on intensity and duration.
- Training for 30 to 40 minutes optimizes the "anabolic-window" high-intensity training provides. Going beyond the 40 minute threshold places you outside the optimum hormonal response time.
- Training beyond 40 minutes increases the risk of over-training and increases catabolic hormone secretion. As you drift outside the "anabolic-window" you enter a detrimental "catabolic" phase. Training beyond 40 minutes decreases anabolic activity.'
