My fiancee has just started training for a marathon so I thought it would be best to change her lifting routine from three days a week to two since she is running 5 days a week. She still wants to lose weight during her training which I'm sure wont be a problem at first because she is burning so many calories, but I know most runners hit a plateau due to constant long distance running. Besides upping her calories, are there any other tips to avoid this plateau?

Here is the 2 day split. Any suggestions?

Workout 1
Squats
T Bar Row
Bench
Incline Bench
Bicep Curl


Workout 2

Deadlifts
Pullups
Dips
OH Press
Tricep Pushdown
