Two efficient training picks
If you want strength plus conditioning in one move, the dumbbell thruster—basically a squat into an overhead press—is being recommended as a complete, time-efficient exercise. Coaches are also pushing ‘vertical training’—stair intervals—to build posterior-chain strength and running efficiency for varied terrain, a practical option for outdoor conditioning.

A lot of people waste 45 minutes splitting “cardio day” from “strength day,” and two coaches’ picks this week try to collapse that into simpler work: one pair of dumbbells, or one flight of stairs. The first pick is the dumbbell thruster, which links a squat to an overhead press in one continuous rep. Fit&Well called it one of the most complete strength moves because the same rep asks your legs to drive the weight and your shoulders to finish it overhead. That “complete” label comes from how many joints have to work at once: ankles, knees, hips, shoulders, and elbows all move in sequence. A single thruster trains the same basic pattern as standing up from a chair and then putting a box on a high shelf. The trick is timing, not speed. You drop into the squat with the dumbbells at shoulder height, then use the force from standing up to help launch the press instead of trying to strict-press the weight from a dead stop. That is why thrusters feel like conditioning even when they are technically a strength exercise. Because the legs and upper body work without a break between them, heart rate climbs faster than it does in slower single-joint lifts like curls or lateral raises. The second pick is “vertical training,” which is a fancy name for deliberately going uphill or upstairs instead of only moving forward on flat ground. Lifehacker’s example was stair intervals, which turn an office tower, stadium section, or park steps into a repeatable outdoor workout. Stairs change the job your body has to do because every step lifts your bodyweight against gravity. That shifts more work onto the glutes, hamstrings, calves, and back-side muscles coaches group together as the posterior chain. For runners, that matters because those back-side muscles are the engine that pushes the body forward after each foot strike. National Academy of Sports Medicine coaching material on running mechanics also points to hip extension and force production as central pieces of efficient stride mechanics. Stair work is not just a trendy substitute for hills, either. A Medicine & Science in Sports & Exercise study found that nine weeks of stair-climbing training produced treadmill and running-performance gains similar to a run-training group. Put together, the appeal is pretty simple: thrusters compress lower-body and upper-body lifting into one rep, and stair intervals compress strength and breathless conditioning into one route. If you have 20 minutes, a pair of dumbbells covers the first option and a staircase covers the second.
