Recently after being badgered by one of my mates to go down the gym, I eventually caved and went, despite not lifting weights for years and being more boxing martial arts oriented. Anyway, we get down the gym and he tells me this is the way you have to do your sets, starting light to warm up with about 12 reps and then go heavy and then heavier still, so you can just about do 6 reps with your heaviest weight on your last set. I tried to explain to him the way I used to do my sets and he wouldn't have it and his way was the only way. Well I went along with his method and I just couldn't get anywhere, I even acquired a shoulder injury that still doesn't feel quite right to this day. So to the old method I learned from body building guides way back when I was a teenager were logical and progressive in a steady way and even though I didn't get massive from this method I definitely got stronger and moved up in weight quicker, with no injuries. Basically, it flipped my friends routine on its head, starting with the heaviest weight you can manage aiming for about 6 good reps. The next set, drop a kilo or two and bang the next set out this time aiming for 8 good quality reps. The final set the same again, drop a bit of weight and do your last set, aiming for 10 or so good reps. Now this method to my mind isn't any easier than the previous method as you will still be lifting the same amount of weight as before, however, your mind will believe it is and for this simple reason. Every set you finish your going to be a little more tired each time, so dropping the weight kinda tricks your mind into thinking you can have a rest next set, which to a certain extent you do, but you still have more reps to do. Using your energy while you have it to get the hardest work out of the way, makes it more likely that you will finish your sets and finish them strongly, with good form! When you feel you are smashing out the set with no bother, try instead of immediately jumping up in weight to do a few more reps, this way when you do move up, you should have less of a challenge adapting to the new weight, as well as I have experienced that sometimes I'm still not quite ready for the extra weight and it only proves detrimental to my form moving up too soon. Its still always a good idea to warm up before doing your sets, and I always generally chose a large muscle group and a small one together, like back and biceps or chest and tri's etc to do together, normally leaving any small muscle group work till last as you will most likely have cooked these indirectly when targeting your bigger muscle group. Also years back I read a book that suggested giving your body no more than a minute break in between sets (or when your breathing returns to normal), which gives a release of testosterone that will aid in your recovery and promote those strength and mass gains as well as making you more motivated and hornier. I'm sure many will be familiar with this method, but in my experience many people were advocating the reverse of this, when it worked for me! Always listen to your body and maybe give this method a whirl if you have never tried it and feel like your workouts are a bit of a chore, it might work for you! Good luck!
