Hello. My situation is the following, I am 50 years old, I am 6.2F tall,,198.4 pounds. I am a smoker (a box of cigarettes lasts me more than a week approximately) I do know anyway what smoking means and for a year I have been significantly reducing the number of cigarettes I smoke. I haven't been able to leave it at all. Between serious problems in my life and the stress of the financial situation that I have been experiencing for several years, I was basically on the verge of committing suicide and I managed to overcome that level of depression, although not completely. I am the father of an incredible 9-year-old son (basically the reason why I did not realize what I planned to do to end my existence)... I have always been relatively physically active, I have been a dirt bike rider since I was a child. and it is one of my great passions but as you can imagine it is an expensive activity so I had to give it up and well I started to gain weight, I started to put physical activity aside and basically forget about myself. Until a while ago, seeing that it was very difficult for me to play with my son, I gained awareness of my condition and I began to jog 4 times a week a couple of miles a day. At first it was super difficult but it is not so difficult anymore, my son has been practicing jiu jitsu since he was 6 years old and decided to try this incredible sport, I have been through 5 classes and I am physically destroyed, my entire body hurts absolutely (even my hair , and of course I know that it is part of the process, I definitely do not plan to stop to go to classes since after enduro for me it is the second most incredible sporting activity I have ever done in my life. Having said that, a little information about my physique, I have had multiple surgeries, they removed a tumor from my back about 10 years ago. years, I have multiple fractures (due to my enduro racing past), 2 surgeries on my spine to remove 2 herniated vertebral discs also about 10 years ago (they didn't work well at all and it hurts every day at all times). I broke my tail bone approximately 5 months ago. Having said that... I lift weights 4 times a week (I have seen an incredible improvement in a few months), I have improved my diet a lot, I managed to stop eating sugar 2 months ago (that was very difficult but I did it). My questions are... 1) I have jiujitsu classes on Tuesdays, Thursdays and Saturdays, as I said before I end up terribly destroyed after each class, can I lift weights the day after jiujitsu classes? For example, right now my arms hurt a lot, last night I had classes and today I should work on my biceps, triceps, front arms and shoulders with weights but I don't know if I should do it... 2) should I run the day after jiujitsu classes? (the cardio in the classes is brutally intense)...3) all my joints hurt from my fingers to my knees, what can I do to improve the condition of my joints? 4) Is it advisable to take anti-inflammatories or pain killers when you are practicing this type of sports or after lifting weights? I ask because I think they may interfere with the muscle growth/repair process after lifting weights. I thank you all for your time and I hope you all have a great week!
