has anyone done upper lower training split
was thinking

week1
mon- upper
tue - lower
weds -upper
thrs - lower
fri - upper

week 2
mon - lower
tue - upper
weds - lower
thrs - upper
fri - lower

or would be best to have upper lower then rest day in between
thing is i like to train everyday as splits my work day up as do it in lunch

want to try something new that havnt done
was thinking german volumes but its fitting it in in lunch break

so any suggestions are welcome
