Workout Notes:
Alt biceps curls should be done one at a time. Both arms need 25 reps.
No rings to dip? Bar dips are fine. No bars to dip? Weighted chair dips will work.
BB skull crushers can be done from the ground as well as the bench.
Cables would work well for those OH triceps ext.
If you have trouble doing those KTS while hanging, try them seated.
