Spinal Fracture recovery

Patient: I had a fall 6 and a half weeks ago suffering a anterior wedge compression fracture of the T12 vertebra demonstrating 10-15% reduction in anterior cortical height.My progress has been good, with me now taking the brace off for several hours at a time. I try not to take any pain killers as i wish to be able to feel how its recovering.I have started walking 2-3 miles a day and about 10 minutes a day walking in my pool.Am i doing too much ,and How long should my back take to fully recover,so i can resume my rowing amd gym work.
