Managed to work out three times this week (although next week's going to be another story). Today with my trainer I did a 40 second plank, then 20 crunches, then a 35 second plank, then 15 crunches, then a 30 second plank, then 10 crunches, then a 25 second plank and 7 more crunches. Also chest press, something she called an Arnold press, squats of a couple different kinds with weights, flys, bicep curls and tricep lifts.
