I'm not going to give you a program.
If you frame the situation as aping a barbell program with dumbbells, you'll only lose. I understand that it's hard to give up on a good streak with any training modality, but you'll get better results if you approach each tool on its own terms.
You won't be able to achieve maximal resistance in low-rep, bilateral, compound movements. But dumbbells still provide access to sufficient resistance if you tweak any of those parameters, and I bet you have other athletic goals anyway. It's time to find them.
Other athletic qualities
The Juggernaut training systems folks have a Limited Equipment Training Template that I find refreshing in how it presents its recommendations: abstract, since specific situations vary, and blunt, because they know folks miss their power racks. They identity five alternative training focii:
- High Velocity/Explosive Movements
- Very High Volume/High Tension Training
- Building Work Capacity
- Introducing New and Neglected Movement Patterns
- Get Healthy
These methods, and developing attributes like speed, explosiveness, muscle mass, range of motion, and joint health, will position you well to better progress at your maximal strength movements once you reintroduce them. For instance, higher work capacity and movement quality transfer extremely well to deep squat training.
I also recommend looking into materials for athletes who are not training for a specific athletic domain. Coaches like Ross Enamait don't bias their training against conditioning in favor of strength. To the contrary, he thrives on high reps, and his tremendous work output gives him impressive strength despite not focusing on maximal strength. (For instance, see Never Gymless.)
Single limb work is going to be key. Think lunges, single-leg Romanian deadlifts, Cossack squats, curtsey squats, one-arm overhead press, one-arm bench press.
It could be mentally engaging to develop familiarity with lots of calisthenic movements. Burpees, jump rope, push-ups, mountain climbers, planks and so on are a whole world unto themselves. We never outgrow the fundamentals.
Maximal-strength proselytizing is useful, but let's not believe the over-the-top hype that high-rep work isn't great and athletic. Circuits with a dumbbell can be brutal. I prefer 5 to 10 minute efforts with two to four (five?) movements and often a short rest period between rounds. Develop a competitive perspective on challenge workouts like the Magic 50 or some of the less-ridiculous CrossFit "names". Don't forget swings (like a kettlebell) as strength/strength-endurance/cardio work.
Odd movements are also tremendously useful for producing all-over strength, as well as body sense. The Turkish get-up is chief among them, but think also of its constituent components (lunge with press overhead, weighted sit-ups, hip heists) plus windmills, bent presses, Atlas swings, and so on. Each of these is a skill to learn on its own, and an exercise to start light with and gradually introduce higher reps and weight if you want to develop a long-term relationship with it.
I said I'm not going to recommend a program to you, but I'll share some inchoate thoughts about how I'm structuring my own training these days.
I spent about two weeks "trying out" movements and workouts, to see which ones felt productive and could fit into a program that met my goals and felt enjoyable while I did it. I settled on several exercises that I would push hard on for strength and hypertrophy, and some other exercises which I would do for skill work, mobility, stability, or conditioning. The first group includes kettlebell swings and pull-ups (weighted and unweighted); the second, things like Turkish get-ups and Cossack squats. I took each exercise easy for the first few workouts while I figured out the set/rep scheme I needed for it.
After about a month of fiddling, I have something like the following. Brackets indicate alternating between exercises. I'm specifically not recommending this for you; it's purely an example of the process.
A workout: [pull-ups, Cossack squats], [Jefferson curls, Hindu push-ups]
B workout: circuit of [jump rope, Turkish get-ups]
C workout: pull-ups (either weighted or unweighted, whichever I didn't do in A), kettlebell swings, windmills
Many movements stayed bodyweight-only for quite a long time before adding weight, but the reps-at-given-weight can progress quickly once reaching that point. For me this applied to both pull-ups and Cossack squats.
