Rucking vs Running vs Cycling: Which One Actually Pairs With Lifting | 361

We break down the three big aerobic modalities for a concurrent training athlete and what each one actually costs you. Running has the lowest barrier to entry and the highest metabolic demand, which is exactly why it interferes with strength the most. Rucking is the easiest way to hold real Zone 2 without the volatility of a run, and the one rule that fixes almost every rucking problem is staying under 30 percent of body weight. Cycling is nearly all concentric, which makes it the cleanest partner for heavy lifting, but it costs you impact, bone density and tendon work, and it needs a bike and a proper fit.

We also get into Dave's six weeks off running with a broken toe and what that revealed about carryover, why runners lose explosive power, how the interference effect ranks across the three, and the programming rules we use: vary session types between interval, threshold and long, space hard aerobic work away from heavy lifts, and take real deloads. Overall takeaway: if you have a specific goal, train that modality. If you do not, pick the one you will actually keep doing and rotate all three.
