You can’t jump from a single 135 warm up set to a 205 work out. You’ll have to give the muscles and CNS time to adapt to the weight.
I start out with an empty bar. So people look at me, let them.
12 reps with an empty bar: 40
immediatly put on extra weight and do 9 reps with 80
immidiatly 6 reps with 120
then sets of 3 reps to move up to your workout weight, gradually increasing the weight so the muscle and CNS has time to get accustomed to the weight.
Take a bit more time to put the extra weight on. 10-15 more seconds.
finally, the workout sets.
In short, the workout you just described is more like a warmup series.[/quote]
This may work for you, but it certainly is not that necessary to complete this amount of warmup sets.
2-3 sets at lower weights, not taken near fatigue–ie 135x8…225x5…go into workout.
For warmup, 5-15 cardio, then 5 min various light shoulder work. Just light front,side,rear lateral lifts works for me. Sometimes I like to do overhead squats with the bar just to get the body going. But back to the original, I don’t feel like you have to make 20 or more warmup lifts for CNS or any other purpose.
