Harri, hope you are keeping well. sorry to hear about tsf.
I'm not much accomplished but will give you an account of what i do if it may help. i generally do spinning class for 1 hour in the gym, followed by reps/ weight training for 45 mins twice a week as a part of cross training.
Reps class involves squats, lunges for legs, bench press for chest, bicep curls, shoulder raises and abs and press ups and abs curls. Typically repetitions are 24 and 2 sets each. Wieght to be used is go asses yourself whilst doing. They say doing 24 reps should be tough, for the muscles to work and grow.
I'm sure others will come along to give a better idea. Good luck.
