In reply to Katie Suddard :
Use the muscles you want to build up. Work strenuously but don't overwork them. For post surgery, I'd probably go lower weight and higher reps.
With weight training, that's very relative. "Higher" reps is probably 8-20, with 10-16 probably the sweet spot.
You want to go close to failure, but not quite hit it. Recovering, I'd got until you hit "technical failure" - your muscles can still exert force, but you're not able to hold a smooth and controlled range of motion. A couple reps like that aren't going to hurt you.
Much like learning performance driving, you will make the most improvement operating at about 8/10, at least as a novice.
I'd create a circuit with multiple lifts that work the triceps, associated major muscles, and supporting muscles. Ideally use free weights (barbell and/or dumbells).
- Bench press
- Overhead press
- Close-grip press (like bench, but hands closer to target triceps)
- Neutral grip dumbbell press
- "Skull crushers"
- Overhead tricep extensions
- Some rowing or other shoulder type movements for support.
Do 3-5 exercises a session, always doing bench and/or overhead press. 3 sets of 8-16 reps. Rest about 1-2 minutes between each set. 2 or 3 sessions per week hitting the same muscle groups with at least one day of rest in between. Increase weight slightly each session. If your equipment gives you big-ish jumps in weight - increase weight one step, drop to 8 reps. Increase reps each time until you hit 14-16 reps for 3 sets. Increase weight again and drop back to 8 reps.
To find your working weights, start with a lower weight. Increase until you max out what you can do 14-16 reps due to strength, technique, or discomfort.
I really like barbells and a good used olympic bar or easy-curl bar and some plates are the best value in exercise equipment.
For cheapest handy cost of entry that will continue to be valuable, I'd get some simple adjustable dumbbells like these. And buy some cheap 10lbs plates when you need the extra weight. We've got a set of these and still use them regularly. Only slowing down because we bought some fancier adjustable dumbbells.
If you're fealing good or want to shift over to including other major muscle groups and want to lift heavier, transition to the Starting Strength program that was recommended to Nicole.
