Hey guys, I am 40 also and I am feeling like I am just hitting my straps. Good habits go a long way. Train hard , train smart, eat well, vitamins for recovery, meditation is great for that too ( recovery) and rest well too. Glucosamine/condroitin, fish oil, vitamin C, plenty of water, use coconut water no added sugar fro post training drink for rehydration and you are on your way.
Yoga is also great for recovery and keeps you stretching and working your core. Many back issues from guard play all have a bearing on health so keep your spine perfect with regular Chiropractic visits (i have been for 4 years straight each week which saved my career) with a reputable practitioner who understands jiu jitsu and MMA.
always warm up well and stay within your weight class as much as you can to avoid shitty injuries which are unnecessary. If you live drill, be careful which ones you do as they can be risky on your health so keep it in mind. I live drill all the time with my students and try to stay within those boundaries. Lucky for me, my top guys are not too heavy.
Happy training!
