I think people underestimate just how powerful a training stimulus sprinting really is and how many different adaptations we can get from it.
Obviously, sprinting makes you faster, but the benefits extend well beyond speed.
During max velocity sprinting, muscles like the

A 200-km swim required nearly 14,700 kcal per day 🏊
This case study used doubly labelled water to measure energy expenditure during a 200-km open-water swim completed over 73.5 hours by a 103-kg former Olympic-level swimmer 🔍
Results 📊
🔥 Total energy expenditure averaged 14,747 kcal/day, reaching approximately 46,600 kcal across the 76-hour measurement period
📈 This equated to 6.17 times basal metabolic rate, placing it among the highest directly measured sustained energy expenditures reported over a similar duration
🌊 The swim took place in 20.5°C water, where continuous conductive heat loss likely added substantially to the metabolic cost of near-continuous swimming
🥣 The athlete consumed around 10,000 kcal/day, using gels, bananas, muesli bars, sports drinks and larger meals approximately every 4 hours
📉 Despite this, the estimated cumulative energy deficit was still approximately 16,600 kcal
⏱️ Nutrition was provided every 20 minutes during brief stops, helping maintain intake without substantially interrupting progress
💧 Daily water turnover reached 14.8 L, equivalent to approximately 0.61 L/hour
💪 The athlete completed an estimated 200,000 strokes, contributing to shoulder pain, blisters and substantial upper-body mechanical stress
😴 Total rest time was around 7 hours, including partial sleep, across the event
↩️ A previous attempt ended after 163 km and 55 hours, when intake was only ~5700 kcal/day and sleep totalled around 40 minutes
⚠️ This involved one athlete, and calculating expenditure required assumptions about respiratory exchange ratio, so the exact values remain uncertain
For extreme multi-day endurance events, success depends not only on physical capacity, but on sustaining very high energy intake alongside realistic pacing, planned sleep, thermal protection and frequent, practical feeding opportunities ✅

Elbow/wrist pain?
>Switch a lot of your “bicep” movements to unilateral variations.
>Can allow better alignment with the joints so you can nail the bicep without issues.
>Bilateral movements “can” for some people like trying to force a square peg into a round hole.
Examples below:
1) Single arm dumbbell preacher curl
2)Single arm cable curl (facing stack)
3) Single arm cable curl (facing away from stack…shown in video)
4) Single arm cable preacher curl
5) Single arm high cable curl

As we progress through GPP, accumulation, and into intensification, we start incorporating more contrast training into our programming.
Contrast training pairs a heavier strength exercise with a mechanically similar explosive movement, allowing us to train high forces

Years ago, as an aspiring exercise science student, I bought into the idea that consuming protein immediately after lifting weights was essential for maximizing muscle growth. However, as I delved more into the research, I became less convinced of its importance.
To gain greater clarity on the topic, I led a study to determine if pre- vs post-protein intake influenced results (PMID: 28070459). We randomized 21 resistance-trained men to consume 25 g of whey protein either immediately before or immediately after training. Participants followed a supervised resistance training program, 3 days/wk. Those consuming protein before training refrained from eating for at least 3 hours afterward.
After 10 weeks, results indicated no statistically significant differences between groups in muscle hypertrophy, strength gains, or body composition. The results are consistent with acute research showing similar anabolic responses to pre- vs post-exercise protein consumption (PMID: 16896166).
The takeaway: Our findings challenge the notion that protein must be consumed immediately after exercise to maximize muscular adaptations. Instead, they support a broader, more flexible peri-workout window in which protein consumed either before or after training can effectively support muscle growth.
It should be noted that the study had a relatively small sample, so the findings should be interpreted with appropriate caution. That said, results align with the broader literature on the topic.
Bottom line: Getting sufficient daily protein is a priority and is by far the most important nutritional consideration for muscle-building. Consuming protein around your workout can be beneficial, but there's no compelling reason to believe you need to slam a protein shake immediately after finishing your last set.

Bent Over Rows - working with 315 for sets of 8-10 here
I really focus on letting my entire back stretch out at the bottom when I perform these, the carryover to the squat and deadlift is outstanding as your back “catches” the weight.

Interesting article on best practices for optimal hypertrophy pubmed.ncbi.nlm.nih.gov/4184… Shout out to @misraetel with Renaissance Periodization for making a video on this study
TLDR: ACSM’s resistance training update. takeaway from data from 30,000+ people and 137 reviews? The best program is the one you’ll actually stick with and most of the advanced rules are optional
What actually moves the needle
-Strength: ≥80% 1RM, full ROM, 2–3 sets, ≥2x/week
- Hypertrophy: ≥10 sets/muscle/week + eccentric emphasis
-Power: 30–70% 1RM and move it fast
-What doesn’t consistently matter: training to failure, machines vs free weights vs bands, complex periodization, time under tension, BFR(Blood Flow Restriction training).
-Bottom line: progressive RT (Resistance Training) on major muscle groups ≥2x/week with solid effort. Consistency > complexity.

For your strongest athletes this does become more of a priority
A good way to get the design efficiency is to superset/tri-set assistance work with your Squat warm up sets
Example:
1A: Squat warm up sets 1-3
1B: Box Jump 3x3
1C: DB Incline Bench 3x8
2: Squat work sets alone
