Moved to SE now. Decided to go with the following cluster although any advice would be appreciated! Still continuing to do the Fighter pullup program on my none SE days.
SE Cluster:
10kg DB Goblet Squats
Pressups
Situps
10kg DB Renegade Rows
10kg DB Romanian Deadlifts
I think that should cover all the bases but if anyone has any suggestions please let me know

Monday
Training:
3x20 Alpha Circuits (1min RI between exercises, 3min RI between circuits)
Stew Smith Shoulder workout finisher
Notes:
Really struggled with the pressups, only managed around 15 before I started struggling which is weird so I'm going to put it down as an off day. I could really feel the renegade rows working my core instead of my back but I'll see how I get on. Everything else was good! Felt tough but I enjoyed it.
