Best Pre Workout for Seniors for Energy and Joint Support

I am sixty five years old and I still love going to the gym three times a week here in the UK. I am looking for a pre workout that is suitable for seniors. I need a bit of an energy boost but I have to be careful with my heart rate and my blood pressure. I am also looking for something that might help with joint support.

I am not looking for a high stimulant product but something that provides a gentle lift and helps me focus on my form. I have seen some supplements that include glucosamine or collagen. Are these effective when taken as a pre workout? I want to keep moving and staying strong as I get older.

What do you recommend for an older lifter? I am trying to stay active and healthy and I would love to hear from anyone else in my age group. Any advice on safe and effective supplements for seniors would be very much appreciated!
