Congrats, you look great.
Haven't done it! As you can see by my photo for 69 years I did without it. Can't do the jumping as I had both knees replaced. I used to Interval running not good for the knees. What I do for each group is 6 reps at the maximum I can do perfect then move the pin to a lighter weight and do 12 reps then move the pin to a lighter weight and do 24 reps. rest for 90 seconds and repeat the set with the 90 second rest. for a total of 3 sets. The only rest I get doing each set is moving the pin to the next weight that takes about 1 second. As it gets easy I have been increasing the reps. I do strength first and cardio last.
Most people do cardio first and then strength training. That makes no sense! doing cardio first will only make you exhausted.
