Re accessory work I've alredy thought about that and it's most likley that my tri's are letting me down as I rarley do any arm work apart from occasional dips/rope pulldown. I've ordered a belt so that weighted dips, skullcrushers (again which I've never done) and narrow bench should help me some improvements in that area.
That said everything is a weakness when I'm only benching 100KGs I guess.
Also would there be any value in having a dynamic day or should I just bench heavy twice a week until I've increased my max a reasonable amount?
Thanks for any advice in advance its appreciated
