I think you're describing strip sets, with short rests and reduced weight with each subsequent set. The thing with your training is that it's made more complicated by the fact you're mixing it with Rugby. In which case I think you mentioned that you have no choice anyway in terms of changing the frequency, for now. Your approach will maintain at least, and could help improve.
When you're not conflicted with Rugby, then try twice a week training using exacty the same training approach. Whether you split it up onto different days is up to you. Try this for 4-8 weeks either with or without the split, and compare results with 4-8 weeks of what you're doing now, without having other sports in the way. That's the only way you'll know, by comparing the effect.
Thanks for reply bro, interesting suggestions.
I only actually drop the weight once. If i was leg raises 220 for say 20 then failed, i would rest 10-15 seconds and use 220 again until failure (maybe 6 reps more). Then i would drop it to maybe 80kg's and after 10-15 seconds more id go again until failure, then rest/apuse another 10-15 seconds and go until failure again.
I think its been working well, my weights have been going up on things each week (iv been recovering enough from the week b4 to meet my rep targets with the new heavier weights)!!
So wen im finished rugby for the season, i should give the upper/lower a try keeping the same routine tho (il merge shoulder/back and chest/arms days....unless i changed it to push/pull)??
The other alterantive i have is do upper on monday,lower on tuesday, wednesday off then, thur upper speed day (cleans db snatches etc), and friday lower speed (speed squats, overhead squats).
As iv said il b sticking with curretn routine for a while longer, im enjoying the improvements and progress, but might make these changes at end of the season.
Opinions??
