Chest / Biceps

Flat barbell press
2 x 8 - 60KG
2 x 8 - 65KG

EZ Bar curl
3 x 8 - 30KG

Peck Deck (benches were full and towers)
3 x 8 - 64KG

Seated Arm Curl
2 x 8 - 80KG
1 x 8 - 90KG

Cable flys

Would it be recommended for me to do 2 x 8 then 2 sets of 6 to try and increase the weight of what I lift?
