The spike is real — and short
Testosterone does rise after a hard session, for about 15 to 30 minutes.1 The biggest spikes come from sessions with plenty of volume, moderate-to-heavy loads, short rests and big muscle groups — squats, deadlifts, presses, rows.1
Your resting level barely moves
What doesn't change much is the number on a morning blood test. Many training studies show no significant change in resting testosterone, even when men get clearly stronger and bigger.1
A meta-analysis in older men found the same: resistance training didn't significantly change their baseline testosterone, while endurance and interval training produced small increases.2
Lift anyway
The strength and muscle show up whether or not your resting number moves.1 And if you're carrying fat, losing it is the lever with the strongest evidence behind it for the number itself.3
Lifting is also the pillar you can't fake. The log shows whether you did it.
What the week looks like
- Four sessions a week. Heavy compound lifts first.
- Log every top set. If it isn't written down, it didn't happen.
- Miss a session, move it. Don't write off the week.
Why the plan dies on Wednesday
Nobody quits lifting because they learned something new about hormones. They quit because Wednesday happened. That's a consistency problem, not a programme problem.
