Warmups should address specific mobility issues or limitations to prepare you for your workout, they shouldn't BE your workout. This is why utilizing fillers - low grade mobility/activation drills - during rest periods are valuable. They save time & allow you to focus on TRAINING
Remember that behind every impressive physical feat you see are hundreds of basic workouts that person did behind the scenes to build up to it. Displaying strength is very different than building strength, and real results come from consistent hard work over time on the basics.
Lets be honest shall we.
You're (probably) not seeing results in the gym because:
1. You're not working as hard as you think you're working.
2. You're eating/nutrition doesn't match your goal(s).
In short: the answer is YOU.
If your clients have poor technique with the "boring stuff" like push-ups, rows, lunges, birddogs, etc......please, fix THOSE (I.e., do your job) before putting in rest-pause deficit deadlifts vs. chains with a 3-3-1 tempo into someone's program.
Appropriate lumbo-pelvic control is a game changer. I’ve yet to see someone improve their push-up technique/prowess and NOT see improvements in other aspects in the weight room. Not sexy, but push-ups can help squats & deadlifts.
To increase speed, sprints need to be short, fast, and allow athletes to recover. Using them as punishment or to make athletes throw up will not improve their speed - it will only teach them to run slowly with bad form.
Want a better vertical jump? 3 ways to improve:
A) put more force into ground
B) put force into ground quicker
C) be less fat
Most people only focus on "A" & "B" - & they're often the athletes w/brutal diets. Lean out while maintaining peak power & you'll jump through the roof.
