Impromptu Strength Test - Has Body by Science Worked?

I went to the gym this morning just to spot my training partner, who wanted to see how his strength had been affected by our 4 months on Body by Science. He only really tested dumbbell bench press and chins, but said be felt stronger.

While there, I was unable to resist trying out a few of the old favourites myself:

Dumbbell Bench Press: 32 kilos per arm, controlled. Felt comfortable - could have done 5, as previously.

Raise-Assisted Handstand Push Up: 3 plates, one rep. Comfortable - could have done 3-5, as previously.

Chin Ups: did 3 - felt as easy as previously.

Hanging Leg Raises: did 5 - felt rusty, but could have done 10 without too much trouble.

Basketball Rollouts: 1 - did feel a little weak in terms of maintaining core rigidity when outstretched.

Romanian Deadlift: did 2 easy reps at 70 kilos. Felt no heavier than I recall for that weight.

The verdict? If I am honest, I was no stronger. However, I was also no weaker.

Yet in terms of time spent doing strength workouts, the last 4 months have seen it slashed from 30-60 minutes a week average to 10-15 minutes.

I wonder whether after 4 months away from these exercises my 'pathways' will be pretty rusty. Perhaps if I returned to them regularly, there might be gains as I readjust. Could this mean in reality a marginal strength gain?

Also, I am still getting fully 'dialled in' to the BBS protocol. If my optimal rest period turns out to be 9 days or more, as my latest experimentation is testing, then I may start to see greater gains.

The only muscle group I am unsure about is abs. They may be weaker. I suspect the workout they get during pull downs is no match for the rollouts I did previously. I could add an abs component to my BBS workout or I could decide I am not too concerned. They seem to look OK.

I was pleasantly surprised that I felt no weaker on deadlift, in spite of my BBS exercises apparently not targeting the hamstrings; but I do think the leg press pretty much nails everything from the waist downwards: I can recall my hamstrings and calves feeling wrecked after a particularly savage 2 minute leg press.

My training partner and I are busting to get back to body weight exercises, circuits and throwing iron around like thugs. But I am determined to follow through the BBS process logically and hopefully establish how it works best for me. I can then go back to other exercises, knowing BBS is always an option, perhaps to break through plateaus or to save time if my life is too hectic for longer, more frequent gym sessions.
