@faithangel2017 I think a 2 second concentric is pretty slow actually. You’re trying to contract the muscle hard and generate force so it should probably be about 1 second unless you’re grinding through the last rep or two. Then the eccentric is more like 2 to 2.5 seconds.
I do like to hold the stretch for a few seconds sometimes. I think there is some science backing up the idea of intra-set stretching. Some protocols have involved inter-set stretching as well. But too much stretching might reduce the ability to contract the muscle hard. This is something that deserves further research I think.
For periodizing rep ranges on your training split:
I don’t think I can write a better plan than some of the ones out there from “experts”, but I’ll try to give suggestions. Whatever program helps you enjoy it and put energy and intensity into the workout is going to be great.
Don’t be afraid to do compounds for high reps too. The weight will decrease a lot but you’ll build muscle. I would make the high reps day into 11-15 or even 15-20. Get a huge pump, blood flow won’t hurt your gains and will probably help!
Watch out for overtraining, especially in the lower rep ranges on compound movements. On isolations, you won’t overtrain your CNS in the same way but you might feel it in your tendons. For someone enthusiastic like you, overtraining is more likely than under training.
In this Mon/Wed/Fri split you have two days of rest before Monday and 1 day between the others. So I’d choose either low reps or high reps on Monday, depending on which is more important to you. Then do the other one on Wednesday.
Going from 3-5 reps, then 6-8 reps two days later could mean the Weds workout is compromised from some CNS fatigue, maybe you won’t be full strength. Doing 11-15 reps two days after 3-5 will have less interference, and two days later you can hit the 6-8 reps better.
I’m not a huge fan of full body workouts because I think you need to warm up for a set or two and find a groove on each exercise. Also if there’s any setup with plates and such, it just takes time.
I think Upper/Lower, Push/Pull/Legs, or other splits have been better for me. Chest+biceps/ Back+triceps/legs, so that the compounds and arms isolations don’t interfere with one another.
Or even deadlift/bench/squat/ weighted chin-ups with some isolations added. Put in a rest day between each.
Side note: weighted chins are the missing compound movement! Deadlifts do hit the lats, but not in the same way as chin-ups and they definitely don’t build the biceps or rear delts as effectively.
But if you’re making great gains with full body workouts, stick to it! And let me know how why you chose them, since it’s not a popular split.
