Jeff, I am 72 and. I want to stay in gym and continue to train, but train smart. I am confused as to how heavy to go. Example Incline dumbbell presses. I am doing reps slow, as you suggest and good form. Is 80% of 1 rep max, at 5-6 reps sufficient For me that is 75lbs done strictly. I am reading about doing lower reps as a senior may be better than doing higher reps. Has to do with Fast vs slow twitch fibers and I am looing fast twitch fibers as I age. I am also a little confused as to how many sets. I know I need to train different than I did when I was 40. I do want to build muscle if possible. Thanks for any advice

I love this video. Thank you.
I am interested in hypertrophy and I'm in my 50's so I am worried about injury the most. The lighter weights with slowing down the movement give me more confidence. I am on the right track and would love any further videos exploring this topic. I am interested in strength but worried about injury at my age.
PS - As a retired engineer I love the graph too! It is your best video I've seen.

I'm 58 YO. I switched to Time Under Tension from myo reps about 10 months ago. prior to that I was doing 3 reps of 10. Myo reps produced results, I got bigger and more defined. (dropping body fat helped too. Time Under Tension, what Jeff is basicly desctibing made me bigger and more defined. My average time in the gym is just under an hour for a long work out and 25-35 min for a short one.

Strength training vs. hypertrophy training (0: 16-1: 09)
The inefficiency principle for muscle growth (1: 10-2: 06)
Applying inefficiency: lat pull-down example (2: 07-3: 23)
Intensity curves (3: 24-6: 29)
The problem with momentum and too light weights (6: 30-8: 14)
Balancing strength and hypertrophy (8: 15-9: 50)
Conclusion and program information (9: 51-10: 17)

Jeff there are 2 types of hypertrophy. Even one for strength. 1. Myofibular hypertrophy which is increase muscle mass or size. The second type is Sacroplasmic hypertrophy equals to muscle strength. So we can’t say what are you training for and say muscle strength or hypertrophy. Because muscle strength falls also in the category of hypertrophy.

Can you do a video on how to train to get lean and stay lean instead of bulking I don't want a big chest or thicker arms or bigger quads. I know runners are lean because of their training, but I'd rather not have to do running and instead use weights and calisthenics. Like, is it amount of reps, or light weight, both Time under tension

This is like the 2. 0 version of the video where he gave a formal of F=MxA. That video Changed so much for me. Because I found myself chasing weight and being injured. But playing with that formula and using it to keep thing fresh and interesting over the past 6yrs has been my life saver. Fewer injuries, better gains, and more fun.

I swear I used to roll my eyes at manifestation lol but then I got my hands on Manifest the Divine by Elena River and actually did the writing exercises. It sounds dumb but it legit made a difference. Helped me slow down and feel more clear. Now I’ve got a job I love and finally got that car I’d been visualizing forever.

It didn’t feel like anything was working until I started journaling properly with Manifest the Divine by Elena River. I’d tried everything else before. The structure made me stick with it and actually stay consistent. And since then, I’ve manifested more peace, better finances, and so many unexpected blessings

For me it wasn’t the vision boards or crystals, it was sitting down and writing. Manifest the Divine by Elena River helped me do that consistently, and it changed the way I think about what I want. Highly recommend if you feel stuck. I manifested a new relationship and a raise in less than 3 months.

Jeff doesn't age and he looks great, he's been looking the same since I was in high school, now I'm a college Graduate with a master's in Cyber Security going from 140 to 185 pounds muscle deadlifting 500LBS, Squatting 350 LBS. Benching 210, going to the gym 5 days a week
Thank you Jeff

What if you let interested in BOTH strength AND hypertrophy Could it make sense to have mixed sets of an exercise, where set 1 may be like your first example, set 2 like second example and so on, for say 4 sets, with equal number of sets (and intensity) given to both types of set

If you’re in your 20s or 30s and think your energy’s fine, it’s not. Do yourself a favor and read book called TestoGenesis Protocol by Angelico. It’s the kind of stuff no doctor or influencer ever talks about. Pure truth about testosterone and how to keep it strong for life.

I don't think changing rep speed will have significant impact on gains when other areas are correct. I base my cadence on getting good oxygen supply, which I find lets me give as much effort as possible, call with smooth control and deliberation, of course.

Loveee this! I didn’t expect anything when I picked up Manifest the Divine by Elena River. But wow it felt like someone finally explained manifestation in a way my brain could accept. Been seeing little blessings pop up everywhere since.

I'll ask you a question right back: Which one, strength or hypertrophy, will improve my blood glucose control Dr. Ben Bikman always says a big muscle is a hungry muscle, but is a strong muscle just as hungry, or even hungrier

Do you think you could break down how to get the most out of a rest day, including how to adjust meals for those days I find myself feeling restless and wanting to work out/continue progressing, so I end up hitting core instead: /

It’s wild how simple manifestation becomes when you finally understand it. Manifest the Divine by Elena River explained things so clearly. I’m seeing movement now in places I thought were dead ends. Still can’t believe it.

But Jeff wouldn't it get into cardio eventually if I do more reps with lighter weight even if it is with intensity and slower concentrated movements And then so would it still be beneficial for muscle building
